I have recently bought a new motherboard to replace my old one. I was uneasy about removing the processor (due to having to apply new thermal compound), however that I seemed to manage the task without to much trouble. The real issue was re-plugging in all the wires that connected to the motherboard, so I am still unknown to where everything goes. I did a lot from memory (although there were still many spare wires) and that seemed to work. Once I had turned on my PC I got a message saying 'Reboot and select proper boot device...' and went online to find a solution to the problem. I tried certain actions and didn't appear to make any progress. At some point my PC shut itself down and will not boot up again. I am unsure on what to do; I took out the processor and there does not seem to be any damage done. Any solutions?
