Re: My new Computer turns off and on by itself
Devil 'puter. ...thinks to self "Must get shot gun..." LOL.
Try unplugging everything that doesn't need to be plugged in and then try turning on. If that doesn't solve things, check the back of your PSU and check to see if the power supply has a regulator switcher. It has to be set 115 volts if your in the US. Your computer will malfunction or not turn on if it's incorrectly set.
Also, you haven't touched anything while the computer was running have you?
