My mouse keeps going to the top corner of my screen !!!! How do I fix this??

Answer 1

Some optical mice have problems with very smooth or uniform surfaces and can think that they are moving when they are not.


Try your mouse on a different surface.


Also try turning it upside down. If it still drifts then the mouse is defective.

Answer 2

make sure the mouse is firmly and correctly plugged in to the computer and make sure there aren't any dents or rips in the plug or the cord and check the monitor too just in case and when all fails get a new one
