Please help? I have an Acer Aspire R14. I press the power on button and all I get is a flashing black screen. The LED lights turn on and then I just get the screen. I've tried f12 and power, f2 f9 f10 enter, ctrl alt delete, esc, everything I can think of and nothing works. I even plugged it into my television and it didn't even send a signal to my television. I don't know what to do. Please help.
