IntelliMouse locks up on scroll


(I am unsure on the video card, above.)

I have an HP 8655 Pavilion PC. The problem I have is frequent pc lock ups or freezes. I have contacted HP support who said to change my configuration from a desktop to a server, delete all the temporary files etc. etc. but this has not cured the problem. The problem most often occurs while using the mouse to scroll up or down a page without using the scroll bar. I'm getting ready to bring the PC to an authorized HP dealer to let them have a crack at it. Any ideas?

I would really appreciate your thoughts.

Do you have an ATI Rage Pro video card and are you using an Intellimouse?

If so, I checked the Microsoft Knowledge Base and came up with the following suggestion (copied and pasted below for your convenience), which could be the cause of the problem you are experiencing If not, try reinstalling your mouse drivers If that doesn't work, I am sorry but I don't have any other ideas (I will say that the advice you got from HP support seems a bit odd).

One last thought--if the problem only occurs when using the IntelliMouse scroll feature, and you can't resolve it using the above solutions, may I suggest following the KISS principle, which is the Golden Rule of computing--Keep It Simple Sam Leave the scroll wheel alone and use the scroll bars instead, and be happy!
