I have a Lenovo R61 Laptop that I purchased this Summer (the system specs should be visible under my name). About a week and a half ago I started to have BSODs at completely random times: about a minute after startup, some time after hitting the sleep key, and when I alt-tabed in Warcraft 3, those are the only three I can remember but there have been seven since they started. Also, I did not installed anything, hardware or software, for a few weeks before the BSODs. I also have had messages telling me that a registry file has been restored, and after logging in I randomly get a message telling me my system has recovered from a serious problem and do I want to send a report. The page the report pops up almost always talks about hardware or drivers being the cause. I have: run memtest for 32 hours (about a month and a half ago) scanned with macafee, avast, spybot S&D, ad-aware, windows defender and malwarebytes (only windows defender and avast are installed) run a disk check defraged my HD Searched online extensively, with no result updated my system from lenovo and microsoft called lenovo run PC-doctor The stop errors I have received are 0x0000000a 0x0000008e 0x00000050 0x0000001a In Depth History About two days after I received my computer I installed Elder Scrolls 4 Oblivion; It did not install properly and I started to get BSODs so I reformatted and everything was fine. About two weeks after the reformatting I installed Oblivion again, and I started to get BSOD again. I called lenovo and they had me send it in twice, once for the memory and once for the graphics card/system board, I believe that they replaced both the memory and the graphics card/system board and they updated my BIOS. The BSODs that I was receiving were rather random though they were more common when the game had been played recently. I ended uninstalling the game and the BSODs stopped happening, I reinstalled the game and the BSODs started again. I ended up just uninstalling the game and I was fine for the last month until they started again, oblivion has not been installed.
