This is the
reason why I use NVIDIA video cards instead of Intel.
It's built into the mom board, not a separate card.
So is mine, but the BIOS allows an external board to be selected.
Trying an external board is probably a long shot, but it is quite a
significant coincidence that you had an Intel problem at the
same time I experienced one. I didn't spend much time trying
to figure out exactly what happened, I just needed the system
up and running asap, and throwing in another graphics board
was easy.
For the record, I don't recall ever having an issue with any
built-in
Intel graphics systems.
