walkies - it's a long shot, but you might try updating your BIOS. go to the website of your machine's (or motherboard's) manufacturer and see if there is a newer version. follow the instructions there.
a blue screen is a general sigh that something is seriously wrong with your machine. those error messages it flashes are only sometimes helpful, and at best point in the general direction of the error. so short of taking your 'puter to a tech to get it analyzed, your main way forward is pretty much re-installing vista. you might be able to do a repair-install (does vista let you do that? i haven't played with it much, not ever had to support it) otherwise you're starting over from scratch. even if you did get the exact wording of that error there are many things that could potentially cause it and few of the sources of the error could be analyzed and remedied remotely (ok, smart-asses, someone could log in to his machine via remote desktop and try their luck... but i'm not volunteering
knowing that your BIOS is stuck in a loop is only marginally useful, what you really want to know is what is causing the loop.

Be sure to do a screen capture. Oh, wait....
well, he could use a digital camera and take a picture of the BSOD - oh, wait, high shutter lag...
