Specs :
X4 640
XFX 7770 Double Dissipation
4GB DDR3 1600mhz
ASRock N68 vs3 ucc

My problem is when i boot up my pc that has been off for a while. and i start gaming ( 100% GPU Load ) my game lags alot and skips alot frames. that continues for about 5 minutes.
After that its fine but still i get sometimes. The game is Frozen with the sound. ater 1-2 seconds the game recovers but the sound is lagging for 1 more sec.

Also while im browsing on chrome im getting Blue Screen Of Death ( Atikmdag.sys )

When i game ( 100% GPU load ) than it sometimes it will happend that my PC Screen loses signal. in order to fix that i have to reboot my pc. When my monitor loses signal. the sound is stock on the moment of losing signal.

i did a burn in test on Furmark 4x msaa 1920x1080 full screen for 1 hour. and had a avarage of 7FPS. withouth any crashing or so
