Hi so My computer is custom built and Recently i have been having problems with turning my my PC on. The only way it turns on is when i flick the on and off button at the back a few or many times. My Cables are connected properly. I did the lamp test and the socket Works just fine but it is not connected directly on to the wall. Everything is fairly new in the PC. I did BIOS update and Reset the computer keeping the files. This is pretty urgent so any help is very much appreciated! Thanks!
