Laptop keeps restartings by itself?

[jember]

Hi,

 

My laptop keeps restarting by itself? I have noticed recently that a lot of error messages keep appearing i.e "Acer Net Tray has stopped working" (this appears everytime i switch the laptop on) and "security centre has stopped working" My laptop is a Acer Aspire 5715Z and I am running Vista Home Premium.

 

Any advice would be appreciated.

 

Thanks

Reboot your computer in Safe Mode and see if it still restarts. If it operates properly, then it's something in your startup routine.

 

* If the computer is running, shut down Windows, and then turn off the power.

* Wait 30 seconds, and then turn the computer on.

* Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again. If F8 doesn't work try F5.

* Ensure that the Safe Mode option is selected.

* Press Enter. The computer then begins to start in Safe mode.

* Log on with an account that has administrator priviledges, usually your own account (NOT the account named Administrator).
