Why does my Computer Reboot Repeatedly?
Sometimes you may find that your computer is repeatedly rebooting because of an error in the lsass.exe file. Here’s how to troubleshoot such an error.
* Go to the “Start” button and click on “Run”.
* On the “Run” line, enter “shutdown -a” and then press “Enter”.
That should “abort” a system shutdown, if the timeout has not expired. However, that is not the end of it. You will need to download the latest windows updates to stop the reboots completely. Also, make sure that you have a firewall installed and enabled, as well as a good antivirus.
