It started with my computer not turning on at all except for the two fans that were hooked up to fan control. The other two fans didn't turn on and they weren't hooked up to the fan control. I checked all the cords. Everything seem plugged in except a couple of extra cords from my power supply.(Pretty sure they were extra because I remember not plugging them in) I checked my CPU fan and ram and they all seemed ok. After that I saw just a small pile of hairs no more than 5-10 hairs. I took them out and hit the power button and everything worked fine so I turned it off and put the side of the case back on. I took it off of its side and then I thought I heard a fairly quite thud and I went to turn it on and nothing happened. So I took it back apart and I saw nothing wrong. I re-checked all the cords and it looked like nothing fell and it was back to the same problem. A couple of hours later I went back to it after a friend telling me to check all the cords again now nothing is happening when I press the power button. Sometimes when I plug the power supply cord back in and hit the switch in the back after messing with the cords it flashes on for just a faction of a second then nothing. That's only sometimes. I'm getting kind of frustrated because I can't find quite the same problem online. Help!
