Answers :

Hook up your computer directly to a surge protector or wall outlet and leave it on for a while and see if it restarts automatically, if it doesn't then you know your computer is fine.

If your computer still restarts automatically even with it not hooked up to a UPS then you know at that point theres a problem with the computer and not the UPS backups that have been plugged up to it. At that point it can be anything from an operating system issue to a hardware issue.

Also if you can verify that the computer is fine without it being hooked to a UPS then make sure the next UPS you get you only hook up the desktop and the monitor to it. This is a good way to make sure not to many items are hooked up to it that may be drawing more amps then normal.
