EVGA GeForce 8800 GTS 640 MB vidoe card,
Intel core2 duo e6700 2.67 CPU,
4 gig OCZ DDR2 800 mhz,
Coolmax 550wt PSU.
System 3.5 yrs old.
I blew out the case, checked the fans, removed the heatsink, cleaned the heatsink, put back together (with thermal compound of course), upgraded the video card driver. currently the CPU is at 54 degrees C, and the video card is at 53 degrees C. Both are about 20 degrees cooler now than before. Never had a problem playing COD 4, but since I installed Black Ops it has been dragging/lagging/freeze,even in SAFE MODE, and then it would shut down. Now it wont even load with powering down. Any ideas would be greatly appreciated.
