Crashing when running 3d apps

[darksmaster923]

What just started happening is when I try to run something 3d, I see it run for a second, then these light red lines appear on my screen. The computer is stuck, but I can move my mouse around. I've gone through this several times but recently, the computer refuses to detect my video drivers. It simply says that "the NVAPI reported no attached nvidia displays in the system". I fear it could be my graphics card failing, or my PSU dying. My system is
AMD X2 4200
Nvidia 7600GT
2 GB ram
Windows XP SP2.

The drivers are also detecting my 7600gt as a 7650GS if that helps.

I have tried to reinstall drivers before they couldn't be detected. Haven't tried right now.

this might be directx problem ...

Check your directx version required for your application and upgrade to latest if required...

Your gpu is overheating, check the fan, clean the card, replace the thermal paste. How old is the card? Some manufacturers have a lifetime warranty, you should check into it.
