I know i have posted this a couple times and since no one has responded i expect no one has had this happen to them before... If my x700 is running any catalyst driver it causes the monitor to blink on and off... usually a couple times in a row... sometimes continuesly... The old drivers SEEM to be more stable.... If i boot into safe mode or uninstall the drivers for the card and let windows run it with a generic driver this doesnt happen however of course you cant play any games with out the drivers installed. Could this be a card issue? Like is it broken or could it be a voltage problem?...I have a 550watt 24pin PSU so i would think the PCI-E slot is getting enough juice... Could the card be overheating?
