Installed new nvidia GTX 560 card, ran fine for 2-3 months but I just started getting random crashes (screen freezes or goes black). I already uninstalled the driver
, ran driver sweeper in safe mode, reinstalled the latest driver 290.36 to no avail although with the new beta driver (290.36) the crashes seem less frequent. dump information and performance report is attached. System is windows 7 professional x64 the machine and the installation is roughly 7 months old.
