Every time he plays any game, at random, usually within 20-40 minutes, the game freezes, the sound loops every millisecond, and his whole computer locks up, thus forcing manual restart.
And I built his computer for him. We've tried switching out power supplies, changing memory slot positions, graphics cards, hard drives, using multiple -dxlevel tricks and the works of it. Yet nothing I can do will solve that issue. I'm starting to feel bad that he spent $900 by the parts I told him to get at our local electronics shop. Here's what we got:
550W PSU
ASUS Radeon HD 5770
Antec case
ASUS P8 P67 EVO motherboard
6GB of RAM
1TB Samsung hard drive
Windows 7 home edition
And yet his computer is fine without playing games, but once started, it starts the locking up stuff. Any suggestions?
