A couple of weeks ago my computer started to randomly freeze up, anywhere from immediately after the login screen to 2+ hrs of uptime. Now, I can't get past the login screen without the computer freezing. I'm able to get into safe mode without any errors, and after some research I've done the following: This thread showed a similar problem, so I've removed Daemon tools and disabled SPTD: http://windows7forums.com/blue-screen-death-bsod/54654-no-crash-safe-mode-seemingly-random-crashes-otherwise.html I then analyzed my most recent .dmp file, and this was the exact error that popped up: Bsod video_tdr_timeout_detected - Windows 7 Forums I then downloaded the most recent nvidia drivers and via the .exe, updated my drivers. Now, when I attempt to boot up my machine, after the login screen I get the BSOD for a second, and the computer resets. I'm at a loss on where to go from here. Any help would be appreciated, thanks.
