Your Questions About Computer Repair Facts

Mary asks…

Is computer repair technician a good field to pursue?

I am aware of the fact that they do not make a lot of money. I just want a job that i am going to like doing. Is this career field really in demand? I live in Michigan and wanted to know are there any jobs here for this field. Although this is a field that i am interested in pursuing, i do not want to go into this field if there are not many jobs for it.

dave answers:

Yes, I have a friend who owns his own computer repair business. He has been in business for about 15 years and has a little shop. Computer repair will always be in demand because even when the economy is bad (like now) people need their computers repaired, and especially when the economy is bad (like now) people are more willing to fix an old computer than to buy a new one.

Charles asks…

Will the computer repair store find my private stuff?

My Acer PC has to go in for repair (no kidding, right?). Anyway, I am wondering is there any way to password protect, or do something, so ALL of my private things, in fact anything personal at all on the hard drive, aren't visible to them, without password protecting each file and folder separately?
It feels scary to think that the repair man can have access to my whole life and work information?
Please help and has anyone else ever wondered this?

dave answers:

They absolutely will snoop through everything that they can. If they like your pictures they will copy them. If they like your music they will steal it.

Mark asks…

Helpful Computer Repair Companies; the type that list tools tips and tricks?

I am going to start writing a wiki-book about this subject. the article I wrote before, Computer Repair Technician on wikipedia I guess crossed into a how-to.

I know some sites will say use this($$) or best results this ($$$$$$). I will accept any help with this, and sift though them later.

Also, anyone know a reliable source that says the un-official software suites I see alot of places use, are in fact truly official??

Ad-aware, Spybot Search and Destroy, Etc.

Thanks in advance. :)

George asks…

Has my computer repair guy duped me...?

So he actually came in to repair my laptop & then messed it up even more to the point where it needed to be formatted... so after formatting it, he puts in quick heal AV and leaves...

later i got an email (on my home computer in which this same guy had put quick heal for me like a week ago) saying it looks like your serial number has been pirated or sumthin like that...

btw, the QH he put on my laptop he didnt charge me for (as if to make up for the the fact that it was his mistake that required me to format my laptop in the first place) but has he put a pirated version of my home computer's quick heal... and if so, then is my laptop protected?

also, everytime i try to update my quick heal on my laptop i get all these dozens of pop ups which show me detection of trojans & 'suspicious files' on my C drive in documents & settings.....

i keep getting a red pop up (even as im typing right now, saying 'DNA scan Warning - 'suspicious file' and also an option - 'restore from quarantine, Do not prompt next time for this file' - do i check this box and say ok??

whats going on!! help!

Adrian

ps i also ran my own purchased software of advanced disc cleaner 5.0 & it showed me a lotta junk files namd quick heal!
crazyGuy - thank u! but still does a pirated version like the one he has given me still WORK? cud it be that coz of the pirated version iv now got a virus/malware?
also, do i take the option of 'restore from quarantine,Do not promt me agin about this file next time' option?
crazyGuy - sorry also forgot to mention the email that warned me of a pirated version beng used by someone also mentioned that i need not worry coz quick heal will make sure that version is stopped from working...

dave answers:

O mate !!! Got stuck in real problem !!!!
First of all, do not panic !! There are many Ways to get out of it !! The most simple method is, Just Uninstall ur Quick Heal antivirus, and then install a new antivirus program (not QuickHeal again, i would recomment AVIRA , d best antivirus program, free to download, and d best protection ). After installing the antivirus, first of all update it , and then scan ur system !!!!!! All of the old viruses of malwares will be removed and u get ur system working good for you !!!'

Good Luck !!!

Donna asks…

How to transfer songs and videos from ipod to windows vista computer?

Well, my old computer broke down (it decided not to work anymore) and I just got a new windows vista computer, and its great, but my old computer had all the songs on it, 3000 in fact. I brought my old computer in to a repair shop and they are trying to transfer all of the music, but its taking a long time for that to get done. Is there any (cheap) way to get the songs onto my new computer?

dave answers:

My computer did the exact same thing.

Go to kennettnet.co.uk

There is a software program called music rescue. It takes the songs on your ipod and copies them to your computer. All of your songs will be on your ipod still and also on your computer.

I used it the other day. It took a while and it brings up annoying reminders that you need to register (even though you don't). The reminders are every 50 songs. I had 2,328 songs to go through..

I didn't encounter any problems in using this software. The download is quick and easy and you get all of your songs on your new computer.

Good luck!

Richard asks…

Experienced computer repair folks, I am confused why this is working?

I just answered a question on here a few days ago about using 125 watt processors in motherboards that are not rated that high but my experiment is working right now as I write this. After answering this question I decided to try a backup 4 core 125 watt processor in an inexpensive ASRock N68-S back up motherboard. This motherboard is, of course, rated at 95 watts. I assumed the processor would not even work or fry something on the motherboard just like I answered in the question but to my complete surprise it is running flawlessly. Then I took it a step further and I over clocked the processor and then the RAM. I am doing this knowing and yes expecting the system to come crashing down as I wanted to see on my own how far I could take it before it died. Nothing happened and it has been running overclocked for about 5 or 6 days and it is purring like a baby kitten and it has run for over 10 days all together and has been left on for as many as 4 days stress test without being shut down. In fact the power supply is only a mid grade power supply rated at 500 watts. I am running a high quality Zalman copper cooler that keeps the processor at about 30-35 degrees C. Other than that nothing special is used in this system.

Let me make clear that I am not a Troll and I have many years experience repairing computers and today I run mainframe supper computers for the US government. So I know what I am doing and this does not make any sense as I have seen with my own eyes motherboards that have been fried do to what I am doing right now.

In your opinions what do you think is going on here? Could this model of motherboard been rated higher but due to trouble shooting expenses the board was down graded? Or will the system fail after some time? But that fact that this is even working for this long is what has me confused. Your thoughts please. Thanks.
Exactly kyle f and that is why this system should not be working or something should have fried by now but it is working in fact I am responding to you on it right now. I do know that some computer hardware is made at a higher ratting but some models do not get tested at their higher ratting or something gets rejected to save money and is sold at a lower ratting and price. They do this with processors all the time.

dave answers:

OK, this is simple. You've got a 4-core processor with a TDP of 125 watts. If you do the math, you will see that it maxes out about 31W per core (roughly). You've got a motherboard with power regulator circuits rated at 95W maximum. I doubt if it was built exactly to spec. There might be a little wiggle room in the 95W maximum TDP design of the motherboard, for CPU support. But even if we assume that 95W is the maximum...

If you are running any version of Windows...your first core is probably averaging 50% load, your 2nd core is probably averaging 5% load, your 3rd and 4th cores are idle. And I mean ALWAYS idle.

People don't understand that the software is playing "catch up" to the hardware, for a change. Buying a 4 or 6 or 8-core processor makes ZERO sense unless you are going to be running unix or some other SMP-aware Operating System. If you bought a 4-core processor for a Microsoft operating system, you just bought a very expensive DUAL core processor, actually.

So anyway...back to the power thing.

1st core averaging 50% if it's hammered hard. 2nd core running 5% average. At maximum 31W each core...
Running windows, you're probably maxing out about 31W for the CPU total, and averaging much less than that...for the whole CPU (all 4 cores).

So it makes perfect sense that it would run ultra stable. You are using about maybe 1/3rd of the TDP design off of the voltage regulator circuits on the motherboard.

Depending on how much you overclock, you might be able to push that up to about 40W total from the CPU (all four cores), but I doubt if you will load the voltage regulator circuits of the motherboard much past about 45% of maximum.

The missing puzzle piece is Windows. Windows does not use all four cores. It uses core 1 (about 31W) extensively. It uses core 2 also...but very lightly.

While I haven't tried this experiment myself...if I wanted to try to kill that motherboard, I'd google for some kind of burn-in program based on linux...something designed to give all four cores a good workout. THEN you might get all four cores going enough to make the motherboard VRC cry "uncle". (!)

How to repair a computer which lags due to hard shutdowns?

Hi,my computer is a bit laggy due to the fact that sometimes the monitor does not respond and i need to shut it down with the power button.I asked my dad about the lag and he told me something about FAT-File Allocation Table being damaged by the hard shutdown,and it will cause permanent damage.
Is there any way at all to fix this? When i start up my computer and i click on a program such as my browser or Control panel,it takes about 10 seconds to load it and if i click on it it will show a Not Responding beside the program name and it turns white.
Thanks so much for your feedback guys.
I already run Chkdsk with those privileges,it took about 2 hours but after that it still is slow.
As for the other answer,well it is only slow during startup.After about 10min after startup it seems to work fine.
I have searched using Spybot SnD,AdAware and Malwarebytes antimalware,just cant seem to find a problem with it except that it lags a lot post-startup.
Lol thanks you two for the feedback,i fixed it,it still lags a bit but it doesnt go to Not responding,so i am pretty happy with it.
I found out that Ad-Aware and Spybot SnD do not co-exist with each other,they seem to cause problems with my programs and screw things up,so i deleted Ad aware and now its perfectly fine.

dave answers:

Can you go into more detail about the problem? Is your computer only slow right after it has started up? Or it is always slow? Is everything slow? Did it gradually get slower, was it always slow, or did it suddenly just get slow one day?

I don't think your performance issues have anything to do with hard shutdowns. But it's hard to be sure because you really don't go into much detail.

Your Questions About Conficker Patch Kb

Nancy asks…

Do I have the conficker worm, or is it a mimic?

The other day the text under my desktop icons lost all transparency and now have a blue bar around the text. So I opened mozilla to find a solution, and norton's notified me of an attempted attack. Weird, I thought.
Details:
An intrusion attempt by put.ghura.pl was blocked. And then some from click.winrar2009.cn, and goasi.cn. All being a HTTP malicious PDF Request.
So i ran a scan, found ten things (there's usually only one low level tracking cookie), it fixed them. Tried to run live update, wouldn't connect after ten minutes. I opened mozilla, then another attempted attack, and the microsoft site wouldn't open. System restore points are still there, but the fail to restore. Turned off the computer, got out my laptop and started investigating. Seems as though I have the same symptoms as conficker. Downloaded all of the 'official' conficker removal tools, including windows malicious software removal tool. None of them found it, not even in safe mode. The malicious software removal got to the end of the scan and then stayed on the one file, and the 'scan time' started to update every 3 seconds.

I followed the guide at http://support.microsoft.com/kb/962007 and downloaded all the recommended patches and stuff. Didn't work.

Running win xp home 32-bit, norton's internet security 2008.

dave answers:

There is a test to determine whether your computer is infected with Conficker or not. The test can be found here: http://www.2-viruses.com/remove-conficker

Your Questions About Computer Repair Software Toolkit

John asks…

Putting together a Network Technician Toolkit?

I'm putting a network/pc repair toolkit together and I am finding that usually I am one if not more tools short for the jobs in question. The work is mainly standard Computer repair on hardware faults, resolution of software related problems on multiple platforms and networking/security support (on site).

Currently the kit I bring with me usually is as follows:

Bag
Netbook (dual boot windows/linux)
2 x wireless dongles (atheros and ralink)
All workstation Windows OS' and others
Software Diagnostic pack
50 piece toolkit including earthing strap etc
Portable SSD (128gb) hard drive
4x USB flash drives (8gb)
4x Video Adapters (vga->dvi etc)
Wireless mouse/soft-keyboard/headset
Usb DVD drive
Various cables (networking/AV)

I doubt ill be doing any 100 node roll-outs anytime soon, but I'm looking for an experience tech who can tell me about the vital items im missing if possible,

Thanks

dave answers:

If possible, try to include a cable tester. Simply hooking up an ethernet cable to the netbook will indeed tell you if the connection is solid, but, if it isn't, then you need a tool that can not only tell you if there's a problem with the cable, but where it is (distance-wise from the tester itself). Otherwise, it looks like you have a pretty good set of tools.

I've found (for network troubleshooting anyway) that BackTrack Linux can do a LOT of penetration testing and network security auditing, especially for wireless networking. Consider using it if you are serious about network security troubleshooting and testing.

Also think about bringing a multimeter with you. You'd be surprised how many computers have issues due to a bad/failing/failed power supply.

Susan asks…

Why is cost a consideration ?

<<The Royal Navy and BAE Systems plc were pleased as punch yesterday to announce that their implementation of Windows for Submarines™ is complete ahead of schedule. Windows boxes on Ethernet LANs are now in control of the UK's nuclear-propelled and nuclear-armed warship fleet.

The programme is called Submarine Command System Next Generation (SMCS NG), and uses varying numbers of standard multifunction consoles with two LCD screens, hooked up on an internal Ethernet network installed on each sub. Initial reports as the programme developed suggested that the OS in question would be Windows 2000, but those who have worked on it have since informed the Reg that in fact it is mostly based on XP.

BAE and the Navy say the project has completed early, as many of the systems were installed extremely fast. The entire command system of HMS Vigilant, a Trident nuclear-missile submarine, was apparently replaced with the SMCS-NG Windows LAN in just 18 days, according to BAE. The use of commercial-off-the-shelf technology is expected to save the taxpayer as much as £22m in support costs over the next ten years - a bit more than £2m a year, or about a thousandth off Trident's running costs.

“This is a fantastic achievement," said Captain Pat O'Neill. "From speaking to operators and maintainers, I know how much they like SMCS NG. BAE Systems' work is proof that we can get commercial off the shelf technology to sea quickly and support it affordably."

Many in the software community have viewed the Royal Navy's wholesale move to Windows-based command systems with concern, feeling that the savings are not such as to justify possible losses in security, reliability and assurance. In addition to the existing nuclear submarine fleet, the RN will use similar equipment to handle its new Type 45 destroyers in combat, and versions of SMCS-NG will also lie at the core of the upcoming Astute-class subs.

Here on the Reg naval desk, we'd go relatively easy on submarine worries - even the Trident boats - as sub command LANs are by their nature very isolated and physically secure, and submarines almost never need to give their command systems autonomous firing authority.

By contrast, however, an air-defence destroyer like the Type 45 - if it is to be much use - will fairly often have to give its collection of Windows boxes the ability to loose off a sheaf of Aster missiles without human authorisation. Shooting down the possible supersonic sea-skimmers of tomorrow will be even more impossible with the delays of having humans in the loop.

Just to add to the slight feeling of nerves, a destroyer LAN will need to be connected to other networks off the ship as a matter of routine, and physical access to a destroyer is hugely easier than to a sub as well.

So we aren't really looking at Windows boxes triggering nuclear armageddon if something goes wrong here. But we just might, if things go wrong, be looking at a computer snag causing another USS Vincennes airliner shootdown disaster in coming years. Or, of course, at British sailors of the future staring helplessly at what would shortly be literally a blue screen of death, as the shipkillers bored in without response. ®>>

Terrific if the system works, as they then have a working model they
can use to leverage quality.
DOESN'T mean to say the BAE system has to be necessarily be used at sea.

Ken asks…

With all these great things. What was so bad about the Nazi's?

Statements on the Internet on what the Nazis invented/ contributed to the modern world
Volkswagen
KdF
computer, invented by Konrad Zuse 1941.
Jet plane in 1939 by Heinkel Flugzeugwerke.
The first manned rocket flight in 1945 (unfortunately it lasted only some seconds and pilot Lothar Sieber died)
Nazi doctors, in line with their campaign for public health were the first to write a major scientific paper linking smoking with lung cancer, I believe smoking was even banned, for a brief time in the Luftwaffee.
Nazis invented Nerve gasses Sarin and Tabun.
Invented first effective automatic rifle, single person anti-tank weapons (precursors to RPGs).
You can see some magnificant architecture by Speer that was planned in nearly any documentary on the man.
Autobahns
Stealth technolgy was invented by the Horten brothers during the Reich.
Audio technology using magnetic tape was a Third Reich invention. Copying German tape recorders was how the famous American corporation Ampex got its start. Magnetic tape was also essential later for the video tape recorder. Allies hadn't a clue how the Axis was transmitting speeches and programs hours apart to different locations and having them sound "live." It was top of the list of technologies to capture as the war concluded.
Management systems for keeping massive and complex development programs on track was another "invention" transferred to the US, along with its scientists and project managers. These systems allowed the Germans to have developments underway in numerous categories and perform them remarkably well.
The Wankel engine, which is now referred to as the "rotary engine" was invented during the Third Reich. Mazda uses this engine extensively.

Someone mentioned the Autobahnen as really an idea thought up during the Weimar Republic. Yes, but that brings to light another achievement, and that is simply the will and energy to put unemployed workers to work doing things that needed to be done, something the Weimar government was totally inept at doing. "Parliamentary chaos" combined with acquiescence to WWI reparations were the problems.

Missile technology: Ground-to-ground, air-to-air, air-to-ground, ground-to-air, ship-to-ship, etc., using wire guidance, TV guidance, IR guidance (everything but laser quidance). Most of these missiles were not at the highest form of development, but their work launched and made a bundle of money later on for corporations like Boeing, Raytheon, Hughes Aircraft, North American Aviation (Rocketdyne Div.), etc. All of these companies had their German "Chief Scientist" heading up research and development operations.

The promising IR technologies were mostly all developed during the Third Reich. They had "night vision" devices while the Allies were still wondering if such things were possible.

Modern sewer treatment facilities are all derived from Third Reich technology. You've probably seen them with their settling ponds and huge skimmers.

While the Englishman, Farnsworth, gets credit for the invention of a very rudimentary television, it was the Third Reich that perfected television and conducted the first broadcasting.

Application of geophones for seismic wave detection was used for locating artillary.

The "wishbone cannon" was invented and installed at Calais, France. It was destroyed before it was operable.

The "rail gun" was another significant invention, which the US and SU copied. This weapon employes a series of ring magnets to propell a rail mounted projectile. The significant feature of this "gun" is that it can accelerate the projectile at a speed nearing infinity -- at least in theory. Conventional explosives are limited by their individual, finite rates of expansion and hence constrained in how fast they can make a projectile move.

The intial "invention" of the Third Reich that made everything possible was the breaking away from the international banking system, which made its money on debt finance; i.e., usury. This act was probably the most important event which caused WWII to later occur. In the Thirties the German economy was booming and all sorts of new humane benefits were granted to workers. Elsewhere, deep economic depression was underway, and Roosevelt, for instance, really couldn't get things to moving until we went into a war economy mode.

In all, 300,000 patents and copyrights were expropriated from Germany by the Allies after 1945.

The Fischer-Tropsch process to produce synthetic fuels from coal, which fueled Germany's armed forces throughout the war.

During the Nazi era, German scientists

dave answers:

Yes, you're right about the inventions and all that stuff. What was bad about them was that they killed 6 million Jews and millions more who they didn't like, had horrible concentration camps where they would put them in gas chambers, had them dig their own graves, starve them to death, and also shot innocent men, women, children, and even babies. They were influenced by one of the most evil men in history, Adolf Hitler. So overall, they were still pretty bad people and there are still Nazis out there even today! So if you talk to people about them, they will still think of them as brutal and evil people. Know this though, not all Germans back then were Nazis. Interesting data you have there.
