Pc startup problems

[Ibonibo]

This is on my workplace pc. so yesterday windows made an update and I quit the office before it had finished shutting down.

Today I arrive and the pc just is messing with me. It still takes power. But the screen stays black. The screen gets a signal but stays black.
When I press the power button on the pc it stops directly. So it doesn't seem to boot at all.

I changed the graphic card.
Nothing.

Changed the psu
Nothing.

All the same.

I now suspect it to be the mobo. Is there anyway to be sure without transplanting the mobo in an other setup.

The mobo is an asrock m3n78d.

The pc doesn't have a case speaker which doesnt help. Anyway to connect the casespeaker to a normal speaker?


Any help would be greatly appriciated

Does the PC have an on-board VGA output?

No and I solved the problem.

Sooo stupid...

I already had the pc packed in to send away. I installed the backup pc. And the same problem.

So it was the Screen which is faulty. 9 months old and all ports have gone to hell

So today was a nice working day:tup:
