Pentium. I hooked the old board back up and everything ran fine
The BIOS should be okay. The G4600 was supposed from version "F1" which I assume is the first version since that goes for every other CPU on the support list.
Where did the CPU come from and is it any good?
Did you have the 8 pin CPU power connected to the motherboard?
GPU power cable connected? (probably a 6 pin)
Try changing RAM slots?
I would try the board again, pop the CMOS battery out first (silver coin looking thing) and see if it will start.
