I've got an old Dell Dimension 8400 that's occasionally getting this error:
I\O card parity interrupt at C000:2100 Type (S)hut off NMI, (R)eboot, other keys to continue
The keyboard don't work so I have to force shutdown to reboot it.
Sometimes it does it again immediately after I reboot, sometimes it doesn't.
This seems to happen before POST, so i'm guessing a part is failing. How can I figure out which part?
