Hi, I hope someone can help! Sorry but I'm not at all technical. A well-meaning friend tried to restore my son's MSI A68HM pc to factory settings but followed instructions for Windows pc. It was on 'egg-timer' all night. Since then we get the MSI logo when we start up the computer but when asked to press <F11> or <Del> we get a 'no signal' message. We tried a different monitor but just get 'no sync' message. Any ideas? Thanks.
