Win 7 x64 crashing my HD 5970
Hi,
A couple of days ago I build a new system with the following specs:
Intel Core i7 920
ASUS P6T Deluxe V2
OCZ Platinum XTC 6GB DDR3-1600 CL7 triple kit
Sapphire Radeon HD 5970 2GB
Western Digital Raptor 150GB
Creative Sound Blaster X-Fi Xtreme Gamer Fatal1ty Professional
Thermaltake Armor SLI Black Window
Corsair HX1000W
Thermalright Ultra-120 eXtreme 1366
Microsoft Windows 7 Home Premium 64-bit NL Upgrade
At first I thought the Graphics card was broken because it kept locking up the screen whenever I entered something 3D, but after days of testing and even buying a new PSU, I know it might be Windows 7 x64 causing a conflict.
I have done all the usual tests, memtest86+, reseating card, fresh windows install, windows updates, tried all graphics card drivers after driver sweeper, disabling windows aero and UAC, Giving the card more vcore, ddr3 on the proper voltage, flashed the bios to latest version, installed latest chipset drivers, ran everything in the system on stock speeds, temperatures are low. Everything in my computer seems perfect.
Here’s the scenario:
I run driver sweeper in Safe Mode, reboot;
I install the graphics card drivers, reboot;
I run benches and a game perfectly fine, maxed out, with the graphics card working on full load and both GPUs;
I perform a different task in Windows (like using IE or installing a program, no matter what task);
I can’t run a single 3D driven application, everything locks up, and the card becomes unusable;
This issue remains until I sweep the drivers again, and reinstall them.
Surely this must be a Windows problem, as the card with its drivers run flawlessly before I start using windows. There's not much to see in the Event Viewer as its a lock up, not a BSOD.
