Hi. Since yesterday my PC is giving me BSOD`s (Mostly on startup/logon, but some of them are random too.) The error codes seem to be 7a and f4. All the files you ask for in the how-to thread are attached. About my PC: Win7 x64 Ram: 12GB Corsair Vengeance triple kit. HDD: Western Digital VelociRaptor 600gb CPU: i7 950 @4*3.06 GPU: Sapphire Toxic HD5850 2GB MB: Sapphire Pure Black x58 Case and CPU are well cooled. Thank you, Gery.
