In many games my video card (I asume it's my card) start acting strange after a while. Sometimes it suddenly uses wrong textures, like putting ground texture on the side of a building, and building texture on the ground. Sometimes it (also) kind of stretches a texture or something like that to form a spike like thingy for just a fraction of a second. When this happens I have a few seconds to try to close the game before my computer crashes. If I succeed at closing the game I have to restart or it will happen again as soon as i enter a game. It seems to be almost garenteed to happen first (after install) time I run a game, resulting in a computer crash requireing a restart. It's also more likely to happen when my computer has been on for a while making me think it might be heat, but i have tried using riva tuner to speed up the fan and watched the temperature, it gets cooler but doesn't seem to make a difference. A few times I have been able to close the game and return to windows although the game crashed (looks like a computer crash), then I get a message about the nvidia display driver crashing. So the driver migth be the problem, but then again the same thing happens on all 3 operating systems and i also tried getting an older driver, still no luck. Games where this has happened: Warcraft 3 (happens a lot in this game, but i have also played it a lot so..) Age of Conan Counter strike 1.6 Red alert 3 beta (well it migt as well be the beta stage in this case) Runescape (played in the browser using java, recently started making use of the video card) Most other games i have tried My setup: Asus p5k – e wifi ap Intel quad Q6600 4 GB RAM 800 MHz, corsair Geforce 8800GT 3 x 1TB hard drives (spinpoint F1), 2 of them in raid 0. Mulitboot XP 32bit, XP 64bit and vista ultimate 64bit are on the raid. Corsair VX550W PSU My 8800gt is from zotac: Graphics Processing Unit - NVIDIA® GeForce® 8800 GT @ 660MHz engine clock - 112 Stream Processors - Dual 400 MHz RamDAC - Max. Resolution @ 2560 x 1600 - True 128-bit floating point high dynamic-range (HDR) lighting with 16x full- screen anti-aliasing Memory - 512MB GDDR3 - 1800MHz memory clock - 256-bit memory bus Bus Support - PCI Express x16 2.0 (compatible with PCIe x16) 3D Acceleration - Microsoft® DirectX®10 support - Unified Shader Model 4.0 - OpenGL 2.0 I think zotac overclocked it a litle (less than amp), am I right or is it only the amp edition that is overclocked? Is my card broken, should I try sending it back to the shop? Or is there something else I should try first, like underclocking maybe?
