I was on my computer browsing the net when the screen went blue and then turned off but the PC kept running normally it seemed. I turned everything off and then powered back on but now I have no display or power to my keyboard and mouse. The PC seems to still start up normally though. I have tried removing ram, CMOS battery and unplugging PSU but the problem still persists. Basically I have no display and no power to other peripherals but the PC still seems fine and can start up. However I can't tell if it is fine because I can't get it to work on my screen or a spare one. Any ideas?
