A few days ago, everything was working fine on the desktop,  I turned if off at night.  In the morning when i turned it on, there was no video.  I was thinking initially that maybe it was a corrupt OS that did not boot and thats why there was no video.  But then I realized that even if the OS is corrupt, you at least get a message on the screen saying no boot device can be found.  So then I went to investigate the video card.  The onboard video stopped working a long while before and I have been using a PCIe video card that by the way is also ASUS.  Anyway I took the card out, cleaned the slot, still no dice.   So then I figured maybe replace it.  So I went and got a PCIe video card to replace this one.  No dice.  So I thought that maybe the slot is burned or damaged.  Next I went and bought a PCI video card since the only open slots were PCI.  Still no dice.  The video just wont work.

 

What could the issue be and is it fixable?

So.. without trying to sound like a smartass here.. why would you think it is a problem with the video when clearly you get a message on the screen that no boot device could be found? (hence video is working telling you the problem)

 

This means that there is either something wrong with the hard drive or hard drive controller.

Okay so the board powers up / fans spin do you get any POST beeps ?  Most Asus boards have some kind of trouble shooting beep codes. .. Are you sure the monitor is still good?

ya the monitor is good cause it works when I plug it into my other computer.  When I turn this computer on (the one that gives no video), I dont hear any beeps, the fans go on.  Sometimes the computer turns on and stays on.  Sometimes it turns on, turn off in a sec and then turn back on and stays on.

I am wondering if this is a power supply problem.  It IS strange that the onboard video does not work also.  It could be that the mainboard has just failed.
