Another computer question thread

[Lady Pi Phi]

I am having computer issues.

Here's the problem: every now and then my computer will beep at me and the mouse will freeze. The mouse only freezes for a few seconds, but it will freeze and then unfreeze anywhere from every few seconds to every few minutes till sometimes not at all.

I's really annoying. Does anyone know why it's doing this and how can I fix it.

Thanks!
