My laptop has all of sudden has stopped working today
When I try and turn it on I get a longish beep followed by 2 short beeps and then just nothing on the screen at all so i have to hold down the power button to turn it off, I know this has somthing to do with the bios but am a bit clueless about what the problem is or how to try and fix it? (its an acer aspire 5010)
