Help! Moving mouse produces beeps, keyboard types 1 per 5 seconds. Only on pc start

[crewxp]

I can't for the love of god figure this out. When starting my computer, sometimes when I open an application, my computer comes to a halt. These things happen:
-Pressing a button on my mouse produces a click for the down press and another beep for the up press.
-If it's bad enough, just moving the mouse will produce a beep
-Keyboard typing is laggish. It types what I type but one letter per 5 seconds about.
-System still loads in the background. People on mumble/skype can still talk in real time. Youtube still plays fine.

To fix it I just have to keep restarting my computer and trying the same thing until it doesn't happen. Does anyone know what would cause this or how to diagnose it?
