Hey, I got this problem for over 6 months now. The BSOD only happens while playing League of Legends. I´ve been playing Diablo 3, Dark Souls etc. alot, but I never got any problems while playing. Those BSOD are kinda unsteady. The only frequent thing about them is, that if I got 1 and I try to reconnect, most of the time I get another one immediatley. As suggested from another thread I tried to run Furmark and Memtes86, both with no results. I couldnt attach my minidump files to the thread for some reason, so I uploaded it http://www.file-upload.net/download-9701429/Minidump.rar.html CPU: AMD FX(tm)-4100 Quad-Core Processor Motherboard: ASUS M5A78L LE Ram : DDR3 2x 4 GB GPU: NVIDIA GeForce GTX 550 TI PSU : LC6550 Silent 550 Watt OS: Windows 7 Every help would be welcome.
