Ok so I was upgrading my PC this Christmas and I was going to upgrade my little brothers PC and build my other little brother one with the part my little brother doesn't need. All I did was move the parts from one case to another and the PC is turning on automatically. When I turn on the PSU the system starts for a few seconds then stops then starts itself again. All the parts were working earlier this morning and I have already reseated the cpu and ram. The PC is using a fx-6300 an radeon HD 5770. The PSU is a 350 watt one that came with an ibuypower pc I used to have. I have tried removing the gpu and booting and that doesn't fix it.
