Hi,

Is this a USB mouse? May be you should reinstall drivers or uninstall in Device Manager, reboot and let Windows recognize it again. Any sign of overheating? To be sure, check the vents/heatsink. Clean them as needed (use a can of compressed air). Also test your RAM for errors using Memtest86+.

If that does not work, try a different operating system. Try Knoppix LiveCD (I encourage you to do this) if it works with your laptop or try PCLinuxOS. Do this so we will know if it is Windows related or something is wrong with the hardware.

If it behaves the same in LiveCD, then it could be the mouse or your motherboard. If it runs fine in LiveCD, then try repairing WIndows, reinstalling drivers or do a fresh install of Windows.

Post back any result of the tests above.
