Can't brick the card OCing with Afterburner or similar, worst that will happen is display driver or PC will crash or game will crash if OC is too high
My display stopped and went into standby mode suddenly on its own (but my pc was running) I had OC my card to 730Mhz before it happened . Do you think my display stopped because of the OC ?
Depends, if you got a "Display driver stopped responding and recovered" message in event viewer at the time that happened, then yes Otherwise, check your power settings for display sleep timeout
power settings for display sleep timeout was set to 3:00 min.. I believe it was not the issue.. How/what to check message in event viewer ? Please do tell
