I was playing around with some of my settings in BIOS to overclock my system and I made a big mistake. I was playing around (rather successfully) at overclocking my Duron 700 to 900MHz using 6.0 x 150FSB. I then entered BIOS again to go back to my default mutliplier but forgot to reset the FSB. So now I don't get any video output and can't get back into BIOS. I've tried cold boots, warm boots, high heeled boots. Nothing is working. Any suggestions?
