No Video signal after a BSOD?

Hi all, i had a Blue screen of death about a fortnight after upgrading my graphics card and doing a full XP reinstall. This BSOD was weird coz it actually errored itself, all i had was just the bluescreen with 2 lines of text and gray bars running downwards all across the screen the rest of the screen had no text at all.

I rebooted the PC and my monitor just said 'No Signal' and since its all the time. I have tested the graphics card in another PC and its fine, i also have identical RAM in my spare PC and tried that as well as my old graphics card and the Mobo graphics port in the 'kaput' PC to no avail.

I am completely lost here, i'd like to think im moderately competant with PC's and have overcome many probs via a quick Google and learnt what to do but with this i cannot find anyone with the same prob on the web, ive even searched all the BSOD sites and forums too.

One thing i really have not bothered learning too deeply so far is the BIOS, would a cmos reset poss cure a prob like this or is it just plain blown CPU/Mobo??
