Recently, I've been getting a strange issue when play games (both online and offline). I play the game, but while I'm playing I experience short durations of severe drop in frame rate. It occurs when I play WoW, CSS, half-life 2, etc etc. It's not lag, because it happens in single player games as well. It was working fine till around 3 days ago, and then this suddenly happened. I reinstalled the driver, and still same thing. Also, sometimes the textures/graphics on the screen don't render correctly leaving objects too shiny or leaving black/red spots on the wall/ground (mostly Counterstrike Source). I performed stress tests, ran 3Dmark tests, etc etc and all those come up perfectly normal. But when I play games, it has frame rate drops. As of now, nothing has helped resolve this situation. temperatures are within normal limits for the CPU, motherboard, video card, etc. All the fans are running correctly. What's wierd is that I downgraded the drive for my graphics card to 158.22 and that resolved that texture problem but it still has the frame rate issue. Here are my specs. Btw, i got the computer like 2 months ago. GPU: EVGA Nvidia GeForce 8800 GTS (640) CPU: Intel Core 2 Duo E6700 2.66GHz Sound Blaster Audigy MoBo: Asus P5N32-SLI SE Deluxe nForce4 SLI Chipset LGA775 RAM: 2 gig PC6400 DDR2/800 Dual Channel Memory Apevia 600W DARK SIDE POWER ATX Power Supply Also nothing is overclocked. Would really appreciate some help with his. Is it a bad graphics card? I mean it's still pretty new and it was working fine till around 3 days ago.
