I have a brand new computer with Windows XP. When I am not on the internet, I unplug the phone line from the back of the computer (Yes, I am stuck in the 90s with dialup). I am extremely careful about the virus software and the window’s updates – I always do them dutifully when prompted. I use the computer as an alarm clock, so it is on all night, but I turn it off during the day while I am at work.
Question #1 – Last night, in the middle of the night, I heard the computer shut down and then the startup music… so I am assuming that it spontaneously restarted. I know of no updates that needed installing. What would cause this to occur?
Question #2 – Occasionally, there is a buzzing or loud humming type noise which pulses slightly coming from the tower. This occurs even when the computer is idling, and happens about once every 2 or 3 minutes and lasts for about 15 seconds.
Thanks for your help!!
