My acer laptop 5920 aspire switches on and off

I'm not sure what you want to "switch of", but to get to Safe Mode, tap F8 as your machine boots.

Look on the side or in front of the laptop for the Wireless Switch. Also once the switch is turned on you can usually toggle the wireless by keystrokes. Normally you would Press and Hold the FN function key located on the left near the bottom on the keyboard then hit the correct F1 thru F12 key that toggles the wireless. The correct F1 thru F12 key to hit will have the icon of a wireless signal )))) or it might have the icon of a tower with the wireless signal )))).

The hard disk has died. Replace it and reinstall Windows.

Creating recovery discs After setting up the computer for the first time, be sure to create a set of recovery discs of the full factory image. the recovery discs are used to start up (boot) the computer and recover the operating system and software to factory settings in case of system instability or failure.

have you checked your bios settings are you booting from the right drive have you tried recovery?

Hi,

First boot in safe mode and the display resolution will be minimal if the screen appears ok with big fonts then try and adjust the normal resolution but not high resolution like 640x480 with 256 colors, if it works then you acer laptop screeen is fine but the exactly display drivers to be reloaded else there is a problem with your laptop screen which needs to be replaced

try pressing on fn+f5 or fn+f6 a couple of times each. Maybe the screen got switched to projector status by mistake.
