Just did a small upgrade to my pc:
XFX 7800GT 256MB Extreme Ed PCI-E @ Stock Speeds.
460W Jeantech powersupply.
I also flashed my bios.
Im quite new to upgrading and this is a major leap for me, but I uncovered a problem. When I play a 3D game such as unreal tournament 2004 or counterstrike source, my pc freezes and my cpu light stays lit. Sometimes the game will freeze for 15secs or it will completely go and restart. This comes after two hours of gaming. I really don't have a clue what could be causing this, I'd guess its concerned with the three upgrades above.
Can anyone help!?
Anything what-so-ever if much appreciated.
