Hi all. Until today i have random BSODs on Windows 7 Ultimate x64. A few months of running pc was ok. Until today. When i am on system , after 5-10 minutes i have BSOD. I dont know what to do. I tested superPi 32mb and without problems, now i am testing MEMTEST and all is ok ( maybe 30 minutes is running ). Even HDTUNE without errors. Just yesterday all was ok. But until today , when i am on system after short time ( 5-10 minutes ) i have just a BSOD. All months of using pc all was stable , no problems. Until today. What now? Please help. Also i used BLUESCREENVIEWER and this is a error log: caused by ---> ntoskrnl.exe+71f00 here is a screen too: My pc is: I7 3770K 3.5 8gb ram DDR3 Vengeance 1600 White Artctic LP Asus Sabertooth Z77 Msi Gtx 680 Twin Frozr Be Quiet Dark Power Pro 1000W Seagate 1 TB SATA III 7200 301.10 WHqL My system is stock, no OC at all.
