Maybe a few weeks ago my computer started acting up on me. My monitor would go into standby and my computer freezes up on me. I have to hold the power button to get it back running again. I took it to geeksquad and they said it was a softwear issuse and i had to destructive reconfig my computer. I just did that and i still have the problem it will stay on for maybe 20 mins if im lucky. Can anyone help me before i take it back to them.
