Hello, thank you for reading. Whats been recently tried : Updated BIOS. Tried Guru3d.com display adapter driver 186.08 Tried Nvidia's 3 versions for Windows 7 (And prior to the RC release I tried some vista display drivers too which worked just as well/bad) Extensive Compatability mode testing Problem : I have a distinct issue with a two Bethesda games, The Elder Scrolls 4: Oblivion and Call of Cthulhu. Cthulhu may crash at any time, but in rare cases almost freezes, sound stutters but goes on, it displays a static corrupted screen with squares that have a pattern that go in a zig-zag manner. Oblivion will also sometimes, everything from 5-30 minutes of game play display the exact same type of corrupted screen if I use HDR Lighting or Anti-Aliasing. If I just use Bloom Lighting it can go hours before it occours. When this usually dominantly green corrupted screen appear a reset is needed to get control over the computer as it will not respond, only continue playing the music with slight stutter. Please help if you can Code: [B]My specs[/B] Build: [B]7100 64-bit[/B] Case: [B]Cooler Master HAF 932[/B] Power: [B]Corsair Powersupply 750W Black, ATX Bulk[/B] Mainboard: [B]DFI LanParty DK X58-T3eH6[/B] Memory: [B]Corsair XMS3 DDR3 1333MHz 6GB CL9[/B] Processor: [B]Intel Core? i7 Quad Processor i7-920[/B] Display Adapter: [B]XFX GeForce GTX 260 896MB PhysX CUDA[/B] Optical: [B]Sony NEC Optiarc DVDÃ‚Â±RW burner AD-7200S[/B] HD: [B]Western Digital VelociRaptor 150GB[/B] P.S. I should mention that GTA 4, and Empire: Total War works flawless, but I was never a real fan. P.S. P.S. Fallout 3 freezes also btw. but it has no screen corruption and music freezes there too, and I saw quite a few other posts about it, so that's for another thread.
