PC suddenly stopped outputting video?

Hi all!
My wife turned on her computer this evening, and nothing showed up on her monitor. It was working fine a day or two ago when she last used it. The computer spins up, fans start, etc., there's just no output. I've tested the monitor/cord combo, and they both work fine on my computer. We've tried both HDMI and DVI, neither appear to be functioning. I think both ports are coming from the video card (not motherboard) but I haven't taken it apart to check or anything like that. I'd really rather not have to do so...
Anyone have any other things I can try?
Thanks!

Tried that, and with the desktop, no luck. The monitor is fine though, I've tested that
As mentioned, I haven't opened it up or anything yet. I'd rather avoid that, but yeah, may not have a choice

If the motherboard has visual POST codes, what are they?
If the motherboard has audio POST codes, what are they?
If the motherboard has video out, enable that in the BIOS and try it.
At that point you're swapping videocards.
I don't know. It's a prebuilt computer, and I can't turn it on to check, of course

Usually if your motherboard has onboard video, one of the slots on the back is actually going directly to it. Watch a few youtube videos to get familiar with the guts of your computer, but try not to get intimidated. If you can follow instructions you can find your way around a set up without too much pain. You're probably going to have to figure out what the parts are inside of the computer so you can look them up individually. Its prebuilt, so you may be able to start by just googling the model and seeing what info is out there.
What brand/model computer?
Unplug the power cord from the tower and let it sit 15 minutes.
My next suggestion is to bonk it. Give it a good thump on the top of the case near the rear where the power supply is mounted. If the fans are spinning up but you aren't getting any combination of beeps. Then it's not actually attempting to POST.
If that's the case, you can maaaaaaybe connect the monitor to that VGA and get it to do something.
Otherwise, you're going to have to get in there, install a spare / cheap video card to replace the current one, and verify that everything else is working by booting with that spare connected to the monitor.

Yes, I've cycled through it. And again it works perfectly on my computer.
Pretty sure there's not an external video port from the MB.
I put together my own computer, so I'm not totally unfamiliar with the parts inside a PC box. I just didn't want to have to open it, but sounds like that may just be best, blah
