I have a i3, 4 gb ram, GTS250x Graphic card.
I was working on my PC, and then suddenly the Monitor screen went blank.
I checked the wire and the everything, the PC was still running.
I tried to restart the pc but made no difference. I attached the monitor on to a different PC, there it worked.
So i removed the graphic card and attached the monitor cable to the On board Video out. There it worked for a while and then again the monitor switched off.
So i opened the case and checked, the fans were rotating for a few seconds and going off. again rotating for a few seconds and going off. This it keeps on doing till of switch off from the mains.
PLease help
