How can I post to Metafilter if I can't see what I'm typing?

My monitor suddenly stopped getting a signal. I did some troubleshooting and don't think
it's a problem with the monitor or cable. What's the next most likely culprit?

I had been using the computer a few hours earlier, it was asleep, and when I went to wake it up there was no signal.
My specs are:
Windows 7 64x
Sapphire Radeon HD 3850 video card
ASRock P45R2000 mobo
4 gb of DDR2 RAM
A Dell widescreen LCD monitor
Here's what I've tried:
-- using the other DVI connection (video card has 2)
-- using a VGA cable with a DVI adaptor (the video card only has DVI out)
-- using a different monitor with the VGA cable and DVI adapter.
-- Plugging the monitor into a different computer using the VGA cable (without the adapter); the monitor worked.
-- I took the video card out of the x16 mode slot and tried it in the x8 mode slot
Other fun facts:
--I can hear my hard drive running, fans running, etc, but can't actually tell if Windows is loading because I can't see anything (I don't hear the windows startup sound, but my sound might be muted -- it often is).
--There are no beeps.
What should my next step be? I don't have any other video cards lying around to try to swap out, or any computers available that I can test my video card in. I don't have any close friends that would be likely to have spare video cards around, but I would be willing to ask around if the video card is the most likely problem.
