my old computer with the new video card
that might be your problem, new cards are at higher speeds, that may be to fast for you mobo....
First is you card agp or pci-e
Second, if agp 4x or 8x...
I wouldnt think your processor would fry.
Would a dead processor do this or would it still be able to go to an error screen on the monitor?
that im not sure..
