allright, I took the cpu out, its just fine, no white crust no burnt core, it has to be either the Power supply- or the motherboard- because the motherboard chipset has been running with just a heatsink on it because the fan died, and has been that way since spring, now I cant even get power to the motherboard, I re-checked everything,hit power button and...... nothing, compared to last night when it would power up just cpu fan wouldnt budge. there is a light on the motherboard that reads "PLED" that is on, so it seems maybe the motherboard is dead but if anyone can help please do.
