For a simple problem like this, maybe I can offer my help. You haven't said you've tried actually using the bootblock recovery method, so I'm assuming you haven't. You need a floppy drive. You know, back in the old days, that wouldn't be a prerequisite... that would be a given.
Once you've dug through your archives of throwaway trash and found a genuine, bona fide, non-USB, honest to god floppy drive, plug that sucker in and now you're up to your next task: finding a disk
to put in that dusty relic. For reliability's sake, you should probably cart the same floppy drive between "doctor" and "patient" PCs, as I've found that drives don't really like reading each others' work sometimes. So be prepared to crack open your good PC as well.
Now, if it's an AMI BIOS, which I doubt it is (since you have stuff on your screen and nobody's used an ISA video card since 1990), you have the easy street... just download your board's BIOS from your manufacturer's website, and slap it on that floppy disc, then rename it to AMIBOOT.ROM.
No AMI? Got Award? Well, it's a little harder, but then again, it's what I wish I had right now in my situation (so I could actually boot a disk and have it force flash my chip and unbrick MY board). You have to make an automated startup disc that automatically runs the flash procedure. You make a boot disk using WinXP's "format" tool or whatever your preferred method is, then delete ALL the files except IO.SYS, COMMAND.COM, and MSDOS.SYS (all the other files are superfluous). Then copy your BIOS and flash tool to the disc. Name the BIOS image something useful like "BIOS.ROM". Then create a New->Text Document. Enter in it the commands you need to automatically flash your BIOS without asking for confirmation or saving the old one. In one example I read, the command may be as simple as (Flashtool's EXE name) (BIOS ROM name) /py - for example, "FLASH763 BIOSFILE.BIN /py". Save that file, then rename it to AUTOEXEC.BAT (ditching the .TXT extension for .BAT). It should change icons - if not, you need to turn off that god forsaken "Hide extensions for known file types" option. Google it if needed. Then shove that floppy in your drive and listen for beautiful happy sounding beeps. Or something on your screen.
Or maybe you just have bad RAM.
Hope this helps! Have a look here
edit: In the future, know this lesson: don't blame your computer. Blame VISTA. Vista is evil. I had to replace someone's motherboard because Vista fried it somehow... =(
