Hi. A few months ago my Acer Aspire 4730z powered off and when I try to power it back on the Acer screen (that comes up normally during startup) shows for about 2 seconds then the screen turns to black with a blinking “_” in the top left corner. When I press some random buttons on the keyboard I hear 4 fairly loud beeps then silence again. If I don’t press random buttons, after a while it starts to beep once every 5-10 seconds or so. Any idea what all this means? Or what I can do to fix it? Thanks.
