sometimes when I turn on the pc, it won't go to post. I have to turn it off and on , sometimes for several times. I noticed that when i turn it on, the cpu fan spins fast and then slows down, then it boots. But when I turn it on and it doesn't boot, i noticed that the cpu fan starts fast, and never slows down, then it doesn't boot. I can't figure out this strange behavior. I have dissasembled and assembled 2 times already, but same problem. Please help. My specs are:
