So my computer was working fine and randomly the screen goes blank and gives me a no signal.

Display wouldnt work so i took out the vid card and cleaned all the dust out, Display turns on for about 5 mins then goes off. The more I try to get it to work the less time the display works it seems.

Weird thing is when the display fails and tells me no signal i can no longer use the power switch or reset switch.
Ive never had anything like this happen I have no idea what it could be.

I put a different video card in that i know works in to it and it did the same exact thing.

Any clues??? thanks for any help at all
 
Had the exact same happen, changing video card didn't help, turned out the cable went bad, switched it to a HDMI cable I use for my laptop and it worked and just replaced the bad cable with a extra one I had once I found it. Cables do go bad.
 
but why when the signal gets lost from the video card i all the sudden can not use the power and reset buttons?
