Any ideas?

I have a very weird problem. My son has a system I built for him 6 months ago. Intel Core Duo processor, Gigabyte MB, 4G RAM, WinXP. A couple of days ago he started seeing graphics artifacts while playing a game. It got worse, and now I have tried replacing or swapping (in order) the:

graphics card
LCD monitor
memory
motherboard
CPU

No luck. You see all sorts of graphics problems immediately upon bootup, even entering BIOS setup, so I don't think it's a Windows driver problem. Any ideas? Could it be the power supply?

Could it be the power supply? Yeah, but with such a specific problem I tend to doubt it. Can you verify the wiring is intact from the PC to the monitor? I only ask because I had a cat that liked to chew on mine (a little dab of hot sauce on the wire cured that little problem). Also check the power cord for the monitor. You say that you've checked virtually everything else, so the only remaining culprits come down to the monitor itself, or how it connects to the system. Good luck.

Yes. Your description of the problem says power supply. I have sworn it was the graphics card all done acting up like that. PSU.

No, I previously tried a completely different monitor and power cable. Same thing. A later commenter says it could be the power supply--I'll try that next.

Thanks!

Just replaced the power supply--no luck. I'm completely baffled. Have replaced or swapped virtually every component in the system. Even took out the soundcard and unplugged the back panel USB connectors. Still a screen full of graphics garbage the minute it boots up.
