The other day I started windows messenger and I needed to update it. So I let it do that and it restarted itself. After that the monitor on the computer will not start up. Its just stays in stand by (amber) mode. I've tried another monitor, and another video card neither worked. All monitors and video cards work on this computer though. Both cards were agp I don't have a pci card to see if that works. There is no onboard video adapter either. I pulled the hard drive and put in this computer and my windows installation was corrupted so I reinstalled. And it worked fine in this box.I put it back in the other computer and no change. I've pulled the CMOS battery as well and nothing. I can not figure out what is wrong.
