Whenever i put my computer to sleep it messes up. When the computer goes to sleep, moving the mouse or pushing the keyboard will not wake it up.. so I push the power button.. but when I do that, it turns on then all of a sudden turns back off within seconds.. it just keep turning on and off by itself until I manually shut it down by holding the power button, this will occur again if I try to turn it on and the only way to solve it is by switching off the power supply, then switching it back on.. it'll start working normally again, what's the problem with it?
