Hello, I am getting the DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) stop BSOD error when i play some games (right now it has only happened in eq2 and DiRT). It usually happens after anywhere from 15min to 2 hours of playing. This is a WinXP SP2 machine. I've tried to eliminate certain components from being the ones that could cause this, here's what I tried: Update BIOS Uninstall, use DriverCleaner, Reinstall nForce and GeForce drivers Run Memtest86+ (passed multiple iterations) Run Orthos, Everest (each ran for 2+ hrs, no errors) So I'm thinking its not my CPU or Memory. I feel like it must be my graphics card. Here's my specs: eVGA 680i SLI mobo, Core2Duo E6700@3Ghz, 4GB (recognized in winxp as 2.8GB) G.Skill DDR2 DDR2 6400@450Mhz, GeForce 8800 GTX@621/1000, X-Fi XtremeGamer Pro, WinXP Pro SP2 Any help would be greatly appreciated. Also, I was thinking maybe I should just upgrade to Vista since some DX10 benchmarks are coming out, are the newer ForceWare drivers almost as fast as WinXP? Thanks to anyone that replies!
