Hi ,
- Have you made any hardware or software changes on the computer?
- Does it happen while using any particular application?
- Do you have a laptop or desktop?
I would first suggest you to try to boot into safe mode and check if the keyboard and mouse is working fine. Safe mode will start Windows 7 with a limited set of files and drivers. Startup programs do not run in safe mode, and only the basic drivers needed to start Windows are installed, follow the steps to boot the computer in safe mode with networking:
i. Restart the computer
ii. Start tapping F8 key.
iii. You will get advanced boot option window.
iv. Select the option “Safe mode”.

Also, change the motion of mouse from control panel.
- Open control panel > Hardware & Sound.
- Click on Mouse.
- In mouse properties, click on pointer option tab.
- Decrease the motion of the mouse and check if it works fine.

If it doesn’t help, download the latest mouse software from the manufacturer’s website and install it which should fix the problem.
Hope the information helps. Please post back and let us know.
