My acer aspire laptop model 5250 won't power on after repeated attempts. I last used it was on a Saturday and that following Sunday morning it would not power on for no reason. When I press the power button the screen stays black, the power indicator lights up and then I get five beeps. and when I listened to them the beeps go: Beeep *pause*, Beeep *pause*, Beeep *pause*, Beep-Beep. I've tried checking other sites for information on the beeps to no success. I know it is not my HDD as I just replaced it after a recent HDD failure, and I tried replacing the RAM stick but its not that. Please help I have to important papers to finish typing and have to retrieve my portfolio. Thank you for your time.
