Actually, I kinda worry that the Hardware Gods have sensed a moment of weakness and attacked. It's that little hint that NOTHING appears on the monitor now that does it. No BIOS I know of can be clobbered THAT hard without a hardware fault somewhere behind it.
I have the impression that you're not a harwdare guru, Jeff. I recommend you find one, because if you don't know what you're doing, you may compound the damage.
In cases like this, the first thing I check is the external cables, just in case something's in sideways and shorting out or malfunctioning. If you are VERY lucky, the monitor cable's loose and that's why you now have no video.
Just because it's fairly painless, at about this point I try and boot from a floppy - either my Win/98 panic disk or the Linux "tomsbtrt" floppy. It probably won't help, but it can't hurt, and if it works, you may be able to recover without attacking the internal hardware.
When that doesn't work, it's time to open the box, check internal cables and make sure all the
cards are seated securely.
When THAT doesn't work, I start yanking out all the
cards and cables and building the system back up from scratch, starting with the most essential stuff until I either have found a defective component or the stupid thing's all back together and I get the BIOS setup program to work again. At this point, you should be working with a hardware expert for sure.
If that doesn't work, then I tear it back down and jumper the BIOS reset on the motherboard. That may seem like a lot of trouble, but I prefer to keep the BIOS settings for as long as possible, and almost NEVER is it necessary to get this desperate unless you've been locked out by a BIOS password.
Somewhere about now, I start to suspect the video card and try it in a known good box. Most of the other stuff is on the motherboard these days - for that matter, so might be the video. So unless the RAM's gone bad, at this point you may just have a toasted motherboard

Or a bad power supply - which if you're REALLY unlucky, toasted the motherboard.
