I built this pc a week ago and it was working perfectly fine until recently where I tried to plug a headphone into a port on the front and i was forcing it and apparently I was plugging it in the wrong way. I then switched it around and plugged it in and the power went through because I saw the light on my headphones but the headphones wouldnt work, I tried a external HD and it lit up as well but never worked. I just said screw that port then but I kept randomly getting popups saying unrecognized usb and my pc was still working for a few days and now it randomly turned off and gives a orange blinking light on mobo and nothing else turns on, no fans or anything just the orange blinking light. I removed the front usb connector and it still seems to have the orange blinking light Anyone know what the problem is? :[ I'm using gigabyte z87x ud3h mobo 750w rosewill hive series if anymore information is needed I can provide

It's possibly an ATX power problem (The 24 pin connector). Get a PSU tester (about $30 on Amazon) and test the PSU with all the connectors. You should have the correct power going through the connectors. Here is a guide to voltage tolerances of a PSU -

If the rails produce less or more power than they should, replace the PSU. If they are showing a good tolerance, leave it. Contact Gigabyte for an RMA of the motherboard and remember to put the black plastic used to cover the pins back over the socket, or they will mail it back broken.

It could be either of those 2.
