My older computer has been slow for awhile but now it won't turn on at all. PSU was ticking and causing a little green light on the motherboard to pulse. I bought a new PSU, hooked it up, so now it doesn't tick. I can short the pins to start the cpu fan but that is all that happens, no bios or beeps from the board (Intel E210882, socket 478). I bought a used board, assuming that was the problem. Connected the CPU, one stick of RAM and the new PSU. Now the PSU is ticking again.
