As title says,

My pc suddenly turned off and fans (guessing the cooling system fans) went on to make high noises and was going on full speed. Left my pc to cool for a and hour and turning it on again made the fans go back to normal speed but when the PC turns on gives 1 normal beep and the monitor just doesn't go on.

Unplugged everything and blew the dust away from the fans.

Never happened before, had my pc with a game on but I was idle and afk.


Update: I found that there was an unplugged wire from my GPU; plugged it back in then everything worked to normal, packed back my pc and everything went back to the same thing, Fan on super high and black screen. I was in a hurry and i didn't check if the plug was unplugged again from packing the pc but I would be worried if both the Fan and the Screen not turning on are different situations.

If the connector for your GPU came off then I'd ask you to inspect the GPU's PCI-E connectors/latches since that is not a normal occurrence. On another note, you failed to mention what your full system's specs were. It might even look like you're experiencing a grounding issue.
