For the most part, you're screwed. You could send the board back to Dell to be reflashed, but it would probably cost the better part of a brand new system.
Cheapest option is to hit ebay and craigslist type sites, look for someone with the same system that they're parting out. Grab the motherboard and swap it for yours. I said it was cheap, not easy.
hello there everyone,
here's my problem i ran into. I was updating my pc's bios from a floppy disk, it deleted the old one and started to install new one. However, it had 0% on istallation line for a long time, so, i just turned off my computer. Not realizing what that will do, i turned it back on only to find most of my hardware working except monitor. Now, i'm stuck not knowing what i should do. Now, i know monitor is working because i had it running moments earlier. I have Dell Dimension 8200 1.8ghz, 256ram, dell motherboard (don't know much about it), 2 hard drives 160gb and 40gb, nvidia geforce2 vidio card.
i couldn't find any treads with similar problem so please help.
