You have to get into the BIOS. There should be a setting to "wake on ring" or something like that. Disable it. Most computers' BIOS is accessed by hitting the delete key while booting. If you aren't sure, watch as the computer starts and see if you can find, at the bottom of the black screen, something about entering "setup" - that'll tell you what key to hit.
If you have a manual for the system, it should tell you a lot about BIOS settings and where to look.
