My new workstation (Win7, Int Core I7 – Nvidia Quadro 4000, SSDs) suffered from a wireless mouse problem right out the box. The wireless mouse was erratic, had mouse jitter and responded sluggish; the mouse would stop for a second and then move again or look like it was vibrating on the screen. Mouse clicks might or might not work.
The PC manufacture said it might be the Bluetooth on the MoBo. So I turned off the BT and WiFi in the BIOS, and went with a wired network connection. The problem was minimized but sill an annoyance. I swapped out several different wireless mice (Logitech Anywhere, HP 3000, MS 6000, MS 3500). They all worked with my laptop but not on the workstation. Moving the mouse receiver to different USB ports reviled that ports on the back of the case were noisier than those on the front side, and that USB3 was noisier than USB2.
I went to a wired mouse for a while. The mouse worked but I don’t want the wire. Back to looking for a wireless solution, I thought I might have something to do with the video card, a video driver, a corrupt USB driver … and spent a lot of wasted time trying to clean this up. I also read a number of post from people with similar issues, mainly using higher end gaming rigs or work stations. Some said WiFi interference, one said he changed the graphics card and it fixed his problem. I found an old MS Laser Mouse 5000 with a corded receiver. It works well with the receiver away from the case or on-top … The problem is 2.4GHz RF noise that affects 2.4MHz wireless mice and/or other 2.4GHz wireless devices.
I believe that the RF 2.4GHz noise is generated from the faster CPUs and/or the CPU/GPU on the graphic card. Without RF test equipment or swapping out parts its guess to the exact cause of the noise. Changing to a 27MHz wireless mouse on a different frequency solved my problem.
