So, recently picked up an asus gtx590 and started having the display randomly go BLACK then come back on after a short time gaming. Overclocking it anywhere past stock clock speed gets the black screen coming and going more often. Possible power supply issue? Had a galaxy gtx480 super oc and oc'd that past stock oc and never had this issue. Tried same 280.26 nvidia driver and installed the new BF3 nvidia DRIVERS and no change. Any thoughs?

Welcome Aboard !Just my luck. Started doing it again. Only after an hour of gameplay. Set the 590 back to stock settings and no change. Sometimes does it after a game is started up.Remove and reseat the ram,on the system and press f8 to safe mode.click on start-control panel-remove programs and remove the game as your pc does not meet the requirement or not compatible.try this and LET see what follows
