PC crash when graphics intensive program starts

stylie

Here is a problem that's plagued me for ages. I get a crash, nv4 display error when ever my pc has to do something graphics intensive. The pc runs fine handling processor intensive programs but for a game,multiple video/pic windows, even fire fox add on piclens she slows down, screen glitch/jumpy and crash, nv4display caught in infinite loop.

I have tested the card Geoforce 8600 with nvidias recommended testing s/w and it passes, I have tested the RAM again ok, mother board and cpu seem fine the only thing I can think of is the PSU, its 350w which I think is to small. Also tested on all new drivers and roll backs.

Any ideas or similar stories ?

It doesn't bother me but I want to sell the pc and cant exactly sell something that crashes

Psu does indeed sound the most likely suspect.
The 8600 requires a minimum of a 350w psu but that;s just a rough estimate as each system's components are different.

Remove all non essential components leaving just gfx card, 1 stick of ram and the hdd with the OS on it attached (remove all other hdd's pci cards and optical drives). If your pc is overclocked be sure to stick it back to stock settings. This is to minimise the draw on the psu. You can then try a graphics intensive application and see what happens. Chances are that it would still crash but if your psu is borderline then it may work. If it does you have your culprit.

I assume you've tried uninstalling and then re-installing drivers and checked that your directx is working properly?

Never thought off reducing the draw on the PSU by cutting down on the drives. Thanks will give it ago when I get the chance.
I have done all the uninstalling and directx test that are available
