Mouse jitters

Window 7 Dell insprion Microsoft wireless mouse. Has run fine up to the last 6 days. The mouse jitters and moves frequently on its own. I try to hit a specific point or option(all) and its hard to get the mouse to go where I want it. I know of no new hardware or software in the last month. Its very flustering at times it just will not follow me. If I circle the mouse several time sometime it will then go where I want it to go but that is a short fix. Sometimes I just slam the mouse down(mad at it) and it will then go where I want it but that doesn't last long. If I shut down foe a while the mouse strars up fine but after an hour or so it goes crazy again Help!

Get a can of compressed dusting gas and blast out the laser cavity. A tiny hair or speck of dust can do this. Make sure the mousing surface is clean too. Beyond that, I agree with plodr - try another mouse.
