I was updating my bios and the screen began to stutter. The mouse moved jerkily, and even sound came through in stutters. Then the display turned off. After that, it wouldn't come back on. Without thinking, I shut down the box. Now the box turns on, but the monitor says "dvi no signal". Please help!!!!

Updating the motherboard BIOS, correct?
From your description it sounds like the BIOS flashing failed midway through which would leave the BIOS in a corrupted and un-bootable state. The 'no-signal' message probably has nothing to do with a video problem. The monitor is simply telling you the PC has sent it no signal which just means the PC has failed to start.
1. I would reset CMOS by pulling the CMOS battery out for half an hour and then put it back in and try to boot again.
2. If that fails then perhaps you should assume the BIOS was corrupted. If so read the manual and see if that board has a "BIOS flashback" feature, from what I can Google I believe it might. If so you may be able to reattempt a flash even while the PC is unbootable - but to be honest I really don't know if that will work.
3. Contact ASUS support. It is quite possible they may have a solution for you.

The CMOS battery is the shiny metal battery sitting right on the motherboard. Un-plug the PC from the wall and then pop out the battery for a while, then put it back, replug the PC and then try to start it. All this will do is to reset the BIOS settings to default. It wont help if the BIOS is corrupted but it is still worth a try. It will not affect your data on the hard drive or your Windows install, just the motherboard settings. It is a harmless thing to try at this point.

Not surprised, that was a bit of a long shot. Back to the original error - if the BIOS was actually in the process of being flashed when your PC crashed then the flashing must have failed or otherwise was been interrupted. Now the BIOS data is corrupt or missing and the only way to ever boot your PC is to try to reflash the BIOS. Of course you usually need a running PC to do that which is a fatal catch-22. However, Asus may have supplied a way for you to do that with the BIOS 'flashback' method or with some other means of recovery. To get to the bottom of this you will need to contact Asus support or speak with someone who has experience recovering a failed BIOS on that particular board.
The other possibility here is that the PC crashed for some other reason and never really flashed the BIOS at all but that sounds like a real long shot to me. Did you see the flashing utility actually start to write to the BIOS when the problem occurred? If so then assume you have a corrupt BIOS and contact Asus support.

That 'loading bar' sounds a lot like the 'progress bar' which you do in fact see as the BIOS is being written too so I would make a tentative assumption the BIOS is corrupt, but still keep open the possibility something else coincidentally failed before the BIOS was actually accessed - perhaps the power supply unit had a partial failure for example.
