I have a computer (with ATX case) that worked fine a couple of years. Suddenly, I cannot start the computer from the power button (nothing changed meantime, not even the location of it). The only solution for strating the computer is to unplug the power supply cord from the socket, stay five seconds and plug in it again and the computer starts (without pressing the power button) immediatly. I've tried to manage this changing the BIOS settings but nothing happened (only the achievment of don't starting at all ... neither with above procedure... There is somebody having a solution for this issue? I know it works but it is a upsetting job to work with power cord every time when you want to start the computer.
