First unplug it from the wall, press the power button a few times to make sure it'll be a "cold" boot. Next plug it in again and try starting again.

EDIT: you said you tried "everything". What do you mean by this? If you let us know what you've tried, we can start ruling things out.

That sounds awfully familiar with Acer desktops... Usually it indicates that the motherboard is dead. You could try swapping out RAM and/or the graphics card. If that doesn't fix it, I'd consider the mobo dead.

His GPU is an onboard VGA. The Geforce 7050 is a lowend built in card.
