While I've heard of this issue, the DSL modem was connected to USB. Fix? Moved it to ethernet.
Other issues are the usual pests and spyware. Does EWIDO and HOUSECALL give the machine a clean bill?
Since I moved and was able to get DSL, when I am online at times, my computer starts making a stuttering noise, sort of like a woodpecker, and the screen shudders with it. Anyone know what causes that?
