Hi, I've been having problems with a pc at work. It was an XP sp2 pc infected with the Conficker worm, and started working badly. I formatted and installed Windows XP sp3, but the pc wouldn't even start. Not even in safe mode. It would simply reboot during windows startup, without even reaching the desktop. It was clearly a blue screen error, but since it was the first boot after installation I couldn't see the blue screen.
Anyway, I decided to try with a sp2 re-installation. It seemed to work at first, but after installing a couple of programs it started giving errors. I tried to reinstall several times but with no luck.
The errors are not blue screens, but application or library errors. explorer crashing, internet explorer crashing, the network subsystem crashing and so on. Or the system item in control panel crashing, too.
I tried changing the drive where the os was installed, with no luck. I also changed the ide cable, no luck again.
So I ran some diagnostic software on the memory: memtest and gold memory. Gold memory is more thorough than memtest and in the past it helped me find some errors which memtest didn't find.
But nonetheless, the system ram seems to be okay.
So I was wondering, might this be due to old motherboard drivers? I didn't try downloading new drivers, mostly because the system became mostly unusable before I could do that.
The pc is quite old, I'm at home now so I can't write the specifics but the motherboard is a Via from some years ago.
I don't know what to try anymore: I also tried installing Windows 7 but the installation stopped each time in the same place, saying a file was damaged or not found. The installation dvd works though, I tested it at home.
