Everything was fine with my pc,then one day i turn it on and my monitor powers on but no display.Only the analog and digital display is on for a few seconds then the monitor turns off.The power button light is blinking,like its on standby.I then unplug everything,plug everything back and turn it back on.This time the monitor comes on,but the bios looks weird,there are jumpled up letters all other the monitor.Once windows comes on there are small blue jagged lines all over the screen.I have no idea what could be the problem,everything else seems to be working fine.I'm guessing its either the monitor or my graphics card,which is a gtx8800.Any help would be greatly appreciated.
