I went to the Dell product page for my computer - Dell XPS 8500, and ran the scan to check for updates.  3 updates, one of them for BIOS.  I ran the updates and initiated the BIOS update.  Midway through it appeared to get hung up and my machine froze.  I left it for an hour, came back and still no luck.

So I rebooted the machine and of course now it won't boot up.  I have power and can hear the fan, but no lights on the box and no screen input.

Looking though the manual and on this forum, I've tried resetting the BIOS jumpers, and removing the CMOS battery.  When I rebooted I saw lights on the box this time but it shut down after 30 seconds, and now back to the same problem.

From what I read on this forum I'm SOL unless I buy a new motherboard.

Just thought I'd check if anyone had any other suggestions.  If not, where can I get  a new motherboard for this?  The product page for my model doesn't list it as an option...

Thanks for your help!
