I have had my rebuilt new computer for a week when i noticed i could not turn it on first time, it took 2 or 3 goes turning on and off from the main socket in wall. I have used 3 seperate surge strips and 2 computer power leads as well as pluging computer straight into wall socket.The computer is a carrera octan 64/6800, the computer can be shut down with no problem any way you like software or silver on/off button on front panel, it just will not start first time.All other devices printer/scanner work fine and come on ok just not computer. I have contacted carrera and they are helping, but i would welcome any advice.I will try to answer any questions, thanxs.
If everything else works that is plugged into the wall socket (try a portable light in the socket, if that works it is not the wall socket) that the computer is connected to I would suspect a faulty PSU in the computer, or the connection from the PSU to the motherboard. Check out the PSU to Motherboard connection by unplugging it from the Motherboard and plugging it back in again. Make sure it is firmly plugged in.
