Computer won't wake from sleep, pixelation

[TomJunior]

Hi,

The boss's computer is having trouble. Whenever it sleeps to a blank screen, it won't wake up. Not only that, but it often has this strange pixelation around the mouse pointer, changing colors, choppy look. He also complained that whenever he ran his CAD program and his photo program at the same time, the computer would lock up and crash.

Found no viruses or spyware. No new software installed.

This computer has run for almost 3 years without a single crash, so I first suspected the video card. Changed from a Diamond Stealth AGP to an ATI Rage 128 PCI and told him to try it out. I also disabled all power conservation settings in the BIOS. A couple hours later he said the problem happened again.

Anybody have any ideas?

Thanks in advance!
Tom

What operating system?

Any Windows updates applied? Direct X? The older cards do not work well with a different variation of Direct X then the one their cd supplied.

I checked it out, and DirectX has not been changed or updated.

Now the computer frequently restarts itself. I think I'm going to just pop in a new motherboard and CPU.
