    I bought these parts and everytime I switch on PC, it just starts for 2 seconds then turns itself off. I thought it might be cpu over heating because I might of not applied the thermal paste thing right but i am pretty sure i did how manual said. I've had it running a couple of times n being able to get on bios, but now i just cant get it to run, sometimes it'll start turn off, then 20 seconds later turn itself on again then turn off. any ideas?

    Take it out of the case, and try to start it that way. It could be shorting against the side of the case.
