This problem has existed for some time and is becoming a real annoyance.
I do not believe that it is associated with my computer speaker system because I can have them "off" and be using only my headphones and, in fact, that is when it is most annoying.
About three months ago, I purchased a nice set of earphones that I could plug into my desktop audio and listen to audio without bothering the boss (my wife).
It became evident, immediately upon headphone use, that I have background noise that is constant. There is a medium pitched beeping sound that has the frequency of a beep a second that is constant even when the system is sitting idle. Every
operation that the system goes through initiates a corresponding, additional, unwanted background sound, including the cycling of the hard drives (I just installed a new (second HD
), the mouse, left and right arrow keys on the keyboard, any every system process generates additional noise. The volume of this interference is "background" level meaning that it is similar to the background noise of one's car engine's RPM coming through you AM station audio in a car that has a radio resister issue.
I, of course, have numerous power cords that connect to a fairly good quality but, six year old power strip that the tower, printer, computer audio speakers and a table lamp.
I recently purchased a new laptop and purchased a logitech wireless mouse for it. I switched my hard-wired track-ball mouse with the wireless mouse and nothing changes.
I have windows XP on one drive and Windows 7 on the other and I get this unwanted noise with either system.
I haven't started to eliminate unnecessary cords that are plugged into my power strip, yet. I thought that I would throw this post up and see if anyone has ever experienced a similar annoyance and have been successful in isolating and eliminating it..
Any help would be appreciated.
My system specs are posted.
