Dead PC - Won't POST



My main PC mysteriously terminally BSOD'd and won't POST any more; just a
flashing hyphen in the top left corner of the screen; as if the BIOS chip
has crashed and burned. It's the INXPense with the Athlon 64x2 4000+ CPU,
2GB Kingston DDR2 667MHz, and Seagate 160GB HDD with 2MB buffer.

(I'm suddenly overjoyed that I've become a backup-aholic of late.)

What immediately springs to mind is that the BIOS always gave a warning
notice at POST

"Warning: CPU architecture not recognised; press F1 to proceed anyway" Or
similar.

- I know; that board is only supposed to take up to and including 3800+, but
it worked happily with a 4000+ until now, (Mine is the only such PC that has
anything more than the intended 3800+ or less, no customers have been done.)
It's been behaving rather strangely lately; and has had a few BSODs which I
thought I'd sorted out.

So I take it I've burnt out the BIOS; that's what appears to have happened
anyway; both from the no-POST state now, as well as from seemingly
overdriving it with the wrong CPU since I built it. I didn't have any other
dual-core CPUs at the time of construction, and someone had asked whether it
would be terminal if anything more than a 3800+ was fitted.

If the fault's as I assume above then I've only got myself to blame; but if
it's otherwise I'm baffled. Does anyone have any thoughts on the matter
before I disassemble the dead machine and attempt some kind of post-mortem
if I have time?
