So I recently built a new machine for my brother. He's been using it for about a month now and had no problems up until now. Now it's not powering up. So, I reseated everything with the exception of the processor and cpu fan. The Power LED light on the motherboard is coming on. I asked him what he did last time he had it on hardware wise and the only thing he mentioned was disconnecting a USB Headset on the front panel where the power switch is. So I thought maybe it could have been a bad power switch so I took a screw driver and tried to manually jump start the motherboard without any luck. I'm now completely out of ideas on what else to look for.. any suggestions would be deeply appreciated.
