I put my computer into storage and once I got it back out, it wouldn't turn on. I replaced the psu already because that's what I was reading might be wrong. The pc gets power, all the lights on the MOBO turn on. Nothing happens when I push the power button though. I have tried jumping the pwr sw pins with nothing but the 24 pin and 4/8 connectors attached from the PSU and still nothing. I am thinking that maybe it's the MOBO but I don't want to replace parts to find out that wasn't it. Does any one have any ideas or tests I can do to narrow it down?
