i had a ps2 mouse on my computer before and i noticed that the curser kept on doing strange things like stopping when im moving the mouse or just jumping around the page. i thought i was just the mouse getting old so i bought a new one, a usb laser mouse. now im thinking there is diffinately something wrong because with this one it is not as bad as the first mouse but i now notice that the curser would just drop and i lose control over it for like 2 seconds. this is strange. i did virus scans and nothing showed up. im about to do a scan in safe mode to see wat happens. if anyone could help it would be appriciated. thanks.

Optical mouse? Throw away the Gateway pad. The black spots confuse the optics.

This problem is often caused by having too many programs running, or too much processor activity from other causes. Check your processor usage with Task Manager. If you have installed any new programs recently check that you have enough RAM, as paging will cause significant slowdowns. Although XP will run on 256M RAM I would not attempt to run any engineering software or CAD (both memory hungry apps) in less than 1GB, and preferably 2GB RAM

Good Luck

Some mouse droppings can contain viruses (i.e. Hantavirus).

Do you have any USB stuff on your PC. Unless it is a high powered PC, USB does drain quite a lot of processing power from the PC.

"Do you have any USB stuff on your PC. Unless it is a high powered PC, USB does drain quite a lot of processing power from the PC."

How do you figure that? Almost everything about USB is self-contained in a separate hardware unit... the processor only sees an interrupt pending when there is data waiting.

"the processor only sees an interrupt pending when there is data waiting"

Actually, USB does not have an interrupt signal. The so-called "interrupt" mode of the USB is actually faster polling. A USB device cannot initiate a USB transfer unless the host device asks for it.
