On Hiatus

My Primary computer that I trade on is sick. I'm still getting the "blue screen of death" (BSOD) after trying to correct it for the last week. Reformated the hard drive, took out TV card and nVidia Video card, re-installed Vista, but still getting BSOD. I suspect I have a virus in the BIOS or some other problem that I've overlooked. It really sucks not having my comptuer running because I can't trade and internet surf.
