So pretty much heres whats going on, or atleast what I'm finding really weird. There are 2 fans in the case, the cpu fan, and a fan in the videocard. one fan in the case and the cpu fan is connected to the motherboard, the other case fan is connected directly to the power source and the videocard is also connected directly to the power source. Now when I turn off the computer all of the fans still run (from the power button). I notice the videocard fan in particular is really loud. the light on the motherboard also is on even though the power key is off (although i think this is this normal) Now it is very difficult to turn on the computer.

EDIT: I just noticed power is not making it to the usb output when the power switches are on...

It takes many times repeating turning off and on the power switch and button to make it work. EDIT: i don't know how i got it to work last time, it's not working now... When the comp is on it works perfectly... I am very confused at what the problem could be. Happy to answer any questions.

I had this problem with an old computer it took about 10 presses of the power button to make the computer come on. It ended up being the power supply. If you have a spare power supply try switching it out and see if the problem goes away.

Was the power suppy faulty or did it not supply enough power? This is a brand new power supply so I don't think it would cause this problem. Although I do have a spare one, but it's old and nowhere near as good. I will try this right now and report back.

EDIT: nope power supply changed and same problem

Thank you for your answer, does anyone else have any suggestionds?

This is just a guess, but sounds like a faulty mobo. If you're sure the PSU is good, then I would RMA the mobo
