updated drivers for ati radeon 7500 to play new game however the card does not support the pixel shader version required - card works fine with new drivers installed.
changed graphics card from ati radeon 7500 to ati radeon 9550 to allow newer games to run. system boots to windows fine, card is recognised and drivers installed fine.
the problem is that the system randomly hangs up, however, doesnt always seem like a normal crash,
1st crash - black and white 2 is loading through splash screens, suddenly screen goes black and monitor light starts flashing as if system has been shut down. computer appears to be still running but cannot get anything to display on monitor
2nd crash - same as above but game gets slightly further through startup
3rd crash - system has booted to windows desktop, while navigating through start menu to load different game screen goes black and monitor light starts flashing as if system has been shut down. computer appears to be still running but cannot get anything to display on monitor
4th crash - tryed different game (Dawn of War) game loads ok. Continue to start playing, when level loads computer freezes with the exception of the mouse which has a black box surrounding it and can only be moved in a vertical direction
Brief System Spec.
CPU - AMD Athlon 2000+
M/board - Gigabyte KT400
Ram - 512MB

I am pretty lost with this one, however i think the problem is driver related as after one of the crashes windows reported an error message stating it thinks the cause of the crash was the graphics driver, unfortunately i did not write down the name of the file in question.
Any ideas / help is much appreciated
