S;ystem boots up itself

By shantie ·
Okay weird one. New system just sold to customer. Everything works okay but after being on the internet, she disconects from net, then shuts down the system. Does not pull out line from computer to extension phone line on wall that an experienced electrician installed. She then goes to a separate room and picks up her hands held house phone, gets a shrieking noise like on internet, then gets dial tone, goes into room where computer is and it has switched itself on??? I asked her to get the extension phone line checked out again, and told okay. I have the system here and does not do it. Remember the system is shut down just the phone line connected, so power is going straight throught and booting system up, I am worried about damaging new system. It is also on a surge board but not for internet connection.
Any ideas thank you

I would put the telephone line through a surge strip that allows the RJ-11 connection just to be on the safe side.

Try a different telephone than the one she has in the separate room--disconnect that one and go through the steps you described previously. If it happens again, then it's not that telephone that's the culprit.

Check the system BIOS for a "Wake on LAN" setting or any power up settings that allow outside signals to start the PC and set to not allow that.

In the System Applet in the Control Panel, on the Startup and Recovery tab, make sure that in the System failure section that the check box for "Automatically restart" is NOT checked.

Review the user's start up and shut down procedures as well just to make sure that there isn't something he\she is doing to cause this (pushing restart instead of shut down, etc.).

Hope this helps.

Thanks for the comments, the automatic boot happened at my place too, did not with the ordinary phone but then tried it with the hands held one and the system did automatically boot. If I disconnected the internet then tried to make a phone call, get the dial tone, then shut down the system would not reboot. Anyway I changed the modem and everything seems to be okay. Might just have been oversensitive modem or not suited for XP but anyway problem fixed, interesting to see if the modem does the same thing on another system with different operating system?? I have kept your comments for future reference. Thanks again
