Having problems with your Computer Speakers ?

When i turn on my compaq laptop, why does it show a blank screen and shut on and of on its own?


Answers :

Its overheating or you have damaged windows. if you see the windows screen, try pressing F8 repeatedly as soon as you power it on and you will see a menu where you can select safe mode. try it and see if it starts, if it wont, or keeps restarting try to boot with a op sys cd just to see if it stays on, if not its the heat. if it does its your windows files and you must reinstall

Nothing worked so she rebooted it again, and all she gets is a blank screen. I am guessing the HDD is shot, but wondered if you had any other suggestions before I buy a new one.
