Windows 7 64 Bit
About 4 days ago my machine started doing something that I have yet to find a solution for.
It happens when I am watching a video file in media player across the network, all of a sudden I will start getting the bell sound at regular, about 1 second apart, intervals.
It seems if I shut down media player and close all windows it will do it maybe a dozen more times and then stop.
There are no messages on the screen, no strange processes that should not be running and multiple virus and spyware scans have turned up nothing.
The batteries have been changed in both my mouse and keyboard to rule those out, both have a power switch on them and turning them off does not stop it so it's not a stuck key or button.
I have never run into this before in all the years I have been on PC's and it's driving me nuts.
