few days back, my xp fails to load and ended up with error blue screen. reformatting, new xp installation, win98 installation, fdisk - nothing helped me. finally i found its due to defected ram. then i replaced that one and installed xp-sp2 successfully.

after a day, when i switched on my pc, my smps became dead suddenly. i bought a new smps and it worked fine without any problem.

2 days later, certain keys ( z, a, q, 1 and esc ) on my keyboard stopped working. i replaced it with another one - not new. but all the keys were worked.

after a day, while browsing, my zone alarm pro indicated 'sethc.exe' tried to do 'something'. i choose to allow this operation. suddenly, some other keys stops functioning - pgdown,end, 1, 2,3,4,7,8,9,0 (keys below f series)

i suspected it might be a virus and scanned my harddisk for viruses, spywares, etc. nothing worth to find the problem. no virus, no spywares....

strange and funny.

what shall i do?

guys, plz suggest.

thanks in advance.

Viruses are strictly software only, there's no way it could have damage your keyboard physically (power surges, on the other hand, could possibly send voltages through the board, to your keyboard connector and then up the cable to the keyboard).

It could just be that you're unlucky in the run of keyboards you've got - it's known as Sod's Law and its perfectly plausbile that you picked up two keyboards that were just about to fail, though of course you had no way of knowing.

I've heard of a virus that affects hardware. It causes the hard drive to freak out and scratch itself. How in the world does it do that, I don't know. This is a very old virus, but still...

Although it is quite plausible that you could of had two bad keyboards, I'd still like to check a few things, just to be on the safe side. :tazz:



Let's first check out the power supply. Download Speed Fan at the following link:

http://www.almico.com/speedfan426.exe

After installing it, start the program. You should see voltages at the bottom, as well as different temperatures on the right-hand side. Make a note of all values for those two sections and post a reply with that info. If you would rather post a screenshot, that would be even better.

Thanks a lot for your input.

I installed 'SpeedFan' successfully. But I can't see any readings as you say. I think, the s/w is not compatible with my pc.

In the 'Readings' Tab, the bottom and right side area having empty boxes only. :(

Any suggestions?

Got one more problem now.

windows scan disk removed some files after i have finished norton scan in safe mode.

now, programs->accessories->accessiblity menu have some links like pr56.tmp, pr5.tmp.

Its interesting that the keyboard tool to enter the key via mouse click also removed in windows disk scan.

That's correct. You don't have sensors for SpeedFan to read. :tazz:

I'm starting to think this is more than hardware. Have your computer scanned by the following online scanners:

Kaspersky's Online Scanner
Trend Micro's online scanner

The Kaspersky scanner does not fix anything, it only allows you to save a report. Let me know how much junk it finds. The Trend Micro will fix problems if it finds them. You may have to start a thread in the Malware Forum. Let me know how it goes.

The Kaspersky scan is clean. The files that were found were handled by Norton already. What did the Trend Micro scan find?
