The connect/disconnect sounds are frequent but random, and only when I am playing games. Sometimes the sound is accompanied by the screen turning black for about one second, but not always. Here is what I have tried so far: Nothing shows up in the event viewer associated to the sounds. I ran a game in window mode, nothing shows up on the task bar as connecting or disconnecting. I updated my video card driver. I ran dell diagnostic, no problems detected. However, I noticed when it was testing the video card, the sounds/screen blanking did occur. I opened the case and cleaned out the minimal dust and made sure everything was tightly connected.

Windows 7 Dell Studio XPS 7100 AMD Phenom II X4 945 Processor 3 GHZ 8GB Ram 64-bit OS AMD Radeon HD 6670 video card

The only things connected to the USB ports are the mouse and keyboard.

I don't know what to do to fix this problem, any advice appreciated.

I am using separate speakers.

What cable do you use? Do you hear through your monitor (via HDMI) or through separate speakers? – Hashirama Senju Feb 12 '13 at 23:58
Don't play the game with the problem? – mdpc Feb 13 '13 at 1:51

I'd try getting updated drivers. Typically I find that this type of problem is due to interference with out-of-date drivers clashing.

I updated the video driver. Can you tell me what other drivers might need updating? – user197789 Feb 13 '13 at 1:55
sound drivers since you are heard stuff though your speakers. In general, I'd make sure ALL drivers are up-to-date. A driver perhaps holding off an interrupt too long or a buggy driver can cause all sorts of weird unepxected things to happen. – mdpc Feb 13 '13 at 1:56
Just a follow up on this... it turned out to have nothing to do with the drivers. I updated every one that I could find. It turned out to be the monitor. Replaced the monitor, no more connect/disconnect sounds or black screens. Tada! Still don't know why. – user197789 Feb 17 '13 at 23:00
