Hello! I'm experiencing a strange problem with my computer. If I slightly move my computer case the pc freezes and won't boot for some several hours. When I try to restart it or to turn it on the power enters in the computer, but the CPU led won't turn on...Actually I think it's because of the CPU but I don't understand why after leaving the pc turned off some hours (5-6 hours) it works normally. This problem has come after I've put a new CPU. I've read somewhere it can be caused by the improper attachment of the CPU fan. Is it possible?
