I have (had) an ASUS P4C800e-Deluxe M/B that was running just fine until I plugged a questionable laptop drive connected via an IDE-to-USB adapter. After connecting, the 2.5" drive banged around a little and then locked up my desktop computer. Rebooted the desktop computer and can't even get to the BIOS. POST voice message states "SYSTEM FAILURE - CPU BAD" or something very close to that. Swapped out the CPU with not luck. Stripped the M/B down to just the processor, a portion of the memory, a keyboard, and power supply -- same error.
Found another P4C800e-Deluxe M/B and transferred all my memory, processor, APG and PCI cards, and it in the case with the original HDD and booted it up. Everything is as if nothing every happened.
So, what happened to my original M/B? What could have died on the USB bus that won't even allow me to get into BIOS? Any help would be appreciated, especially if I can resurrect the original M/B at least for a spare. Thanks.
