Mouse seems to stop computer

I'm not really sure what is causing your problem. What I'm trying to do eliminate things.
If you are using USB ports. Use only USB 2.0 ports. Some have posted on other sites that the ports along the same line your internet cable goes (Cat5) is the ports the USB mouse should be plugged in.

I'm also it might be the fact you computer has only 2 gigs of ram with Windows 7/64.
If things are running in the background using all the ram most everything will be slow or delayed.


Some pictures would help me understand better.

Use this tutorial by Brink to post pictures from your system.

Sorry my mistake here is the tutorial.

You surly have a short supply of ram.
Unchecking all those things except MSE should help. Then reboot.
In my opinion their isn't much you can do with the hardware you have.
Windows 7/64 will run with 2 gigs of ram but it will run poorly.

It would help a little. You don't show your motherboard in your system specs.
Check your motherboard and see if you can add ram.
If you can adding more ram would be my choice.
