Few days ago, my GTX 460 started having "issues". While gaming, the screen blacked out, and recovered (tooltip said the driver crashed but recovered). A few hours later, when I try to start my pc, it BSODs right before the login screen, with the error above. I restart pc, and the error goes away, meaning I can get past the login screen, and game normally for a while. Again, few hours later, the pc crashed, and restarting it gave me the same error. So, I restart again, but same BSOD and error. I'm using a GTX650 as a spare. What I've tried: - switch to my spare GTX650 (works completely) - update to 314.22 and rollback to 310.90 (no effect. still BSODs) - redownload drivers (no effect, my GTX650 works fine with the same drivers) - go in low-res startup mode (works) - go in safe mode (works) - go into safe mode, clean old drivers, go back to normal startup to reinstall drivers(no effect) - do the above then power off pc. Swap GTX650 with GTX460. Restart PC. (worked twice) - boot without overclocks (still BSODs) I think the card may be dead (or almost dead) since: - Device Manager won't let me enable it - Display Settings won't show it - Nvidia Control Panel doesn't show it, either But, GPUZ shows it (gtx460) so I am not sure either. Any ideas?
