a few days ago I bought an unused BH6 from a friend. I installed it, booted up, flashed the newest BIOS, and then turned it off to install peripherals, etc. After this was done, the computer will not boot. The power supply fan will not even start. I tried the power supply with three different motherboards, and get the same symptoms. Unfortunately I don't have any other ATX power supplies around to test the motherboard. Is it possible for the motherboard to have killed the power supply? Might it happen again with a new power supply of the same type?
