I have been having problems with my PC. It turns on for about 8 seconds before turning off and repeating the process. I've done everything I've read online. I've gotten a new motherboard, Tried a new psu, tried new ram, tried new HDD, got new PSU cables, uninstalled my CPU fan to check if there was a short anywhere, also checked all around the motherboard for a short, the PC stays on (With no display ofcourse) when the ram or CPU is disconnected. And yes I've disconnected and tried different graphics cards aswell even tought I know that wouldnt help. If the ram ain't connected even if the cpu is, it stays on and vice versa. I was told that a damaged CPU would NOT cause my PC to fail turning on. I'm out of ideas and I've been on this for a week now. Could anyone help me?
