The chip ended up having no bios image at all, and I just needed to flash it.
Everything booted up 100%
However...
I forgot to put the power supply guard down the first time I reassembled it. So the spikey bottom part of the PS ended up directly on those little fan wires. Imk sure they were pinched, and research has since told me that a pinch of those wires can short the fan fuse.
I fixed the problem and carefully taped the wires someplace safe. But it still wouldnt work after 4 tries.
So I cut off the wires and tested the fan with some batteries, and it still turns.
So now i just have to figure out where to solder the 2 fan wires...
Dont suppose anyone could point out a 5v point on the board or power supply thatll work eh?
