What the frig is wrong with my mouse. The pointer is just jumping to random spots.. Have been using the same mouse pad. Its a dell, came with the computer. Is it a piece of junk that's gone bad? Or does this happen to even the expensive optical mice?
is it wired or wireless? If wireless, the obvious solution is to replace the batteries. Wired, try another mouse just to verify the UBS slot and computer are fine. If a different mouse works great, likely new mouse time. You could also try cleaning the bottom of the mouse with windex or something, just to see if it cleans the path... easy trial.
