I used to get 200-350 fps in CSS EVGA 8800gts 640mb SUPER TALENT 2GB 240-Pin DDR2 800 Intel C2D e6700 2.66ghz 320gb Western Digital HDD Not Software/Virus: Have Reformatted. Notes: On PCfan (or the fan/temp prog.) nothing was overheating except my cpu. I checked it and the motherboard's SMART FAN control stopped it during gameplay sometimes. No damage. Checked CPU speed recording programs and still the same speed. Overclocking worked. Turned off SMART FAN and fan always works. CPU- Stock Cooling... Heard sometimes that might be the root of the problem Motherboard- Gigabyte. No problems. I doubt the RAM and HDD are the problems.. Possibly RAM but low chance. No Problems. HIGHLY DOUBT it's the Vid. Card. No problems. Changing any video settings: 1280x1024 ALL MAXED->1280x1024 ALL LOW->640x480 ALL LOW = All keep a constant 50-100 fps... FPS may be high but it still drops to around 40-50 and really choppy. EDIT: Question: Is it possible for a CPU to be broken, but all the while still function and have a high ghz?
