Open the Activity Monitor >> View >> View ALL processes. Check the CPU tab for a Run Away Process and do the same in Memory tab. Look for usually late COU & Memory process.


Does the same occur when booted in Safe Mode ? Shutdown and restart and immediately hold the Shift key until the Apple Logo is pressed, then release the key. Safe Mode will do a Repair Disk, clear cache files and only Load Apple Software, extensions and fonts. So, it will load slowly - normal. The computer will appear and perform differently - also normal. Run in this mode for 7 - 10 minutes and Test if the mouse movements are normal or not. If normal, there might be some third party software interfering with the normal operation of the computer.
