It worked for a couple of hours and I left to return home. I received a call about 4 hours after I left with the report that my dad had returned to the computer and it was mysteriously off. I thought it was in sleep mode, but he restarted it before he called me so I'll never know.
The computer beeps once ('normal' POST indicator for this MOBO), displays the Gigabyte splash screen and freezes. It will not move forward to POST and none of the shortcut keys work (del, home, tab, F12, etc.) I am under the impression that the computer requires a BIOS update. I have had problems with Gigabyte MOBOs before that were solved that way. Unfortunately, I can't load Q-Flash or the BIOS menu because of the freeze. I attempted a hard reset by reseating the CMOS battery to no avail.
I have not performed a step-by-step check of all the parts (remove all but the CPU, add RAM, add Video Card, etc) because I would have to walk my dad through it over the phone. I did, however follow this list and nothing helped.
