Custom built desktop computer. It was working fine (used as a server), but I needed to change the IP address, so for the heck of it, I went into the BIOS and:
- Loaded factory defaults
- Changed video from PCI Express to on-board VGA
- Saved settings and rebooted
The computer sounded normal and seemed to boot up fine, but there was no monitor signal.
The computer should have been on factory defaults to begin with, but for the heck of it, I looked through the settings, and then loaded factory defaults, and then looked through the settings again. Everything appeared to be the same, and where is should be. Except the video was set to PCI Express.
That seemed strange to me. I didn't catch what it was set to before, but there was no video card installed. I had been using the on-board video. I was afraid that if I saved it and rebooted, I wouldn't get a monitor signal, so I changed it to on-board VGA.
As I mentioned earlier, no monitor signal after that.
Here's what I tried so far:
- Let's assume I successfully went through all the obvious stuff, like power cables, made sure everything was connected, cards seated properly, electricity, etc.
- As I said, everything sounded normal, I'm pretty sure it booted up properly, I just couldn't see anything.
- It's not a laptop, so there's no video out selection to make.
- Was initially using 15-pin cable, so I tried the DVI out with my LCD.
- Wasn't nervous yet, calmly removed BIOS battery for several minutes, in order to reset BIOS to factory defaults, put back, still no signal.
- Followed motherboard manual instructions exactly to clear BIOS, still nothing.
- Followed these instructions (steps 1-10) exactly, still nothing.
So now I'm nervous. I don't know what else to try, except maybe buy a video card to put into the PCI Express slot and see if I get a signal from the card.
Do you have any other suggestions?

- Motherboard: Asus M2A-VM 2nd edition (using on-board video, audio, ethernet)
I did a Google search before I posted and found this link, but I covered that stuff already:

Check the monitor to see if it toggles between analog and digital.
