Sounds like either the grease in the bearings dried/gunked up, or your rollers are worn. Unless you bought it used, it's probably the former since you hardly used it. Try rolling the ball around firmly, or any of the other methods of breaking in the bearings discussed in many other threads. You might want to add grease or oil the bearings, or degrease then regrease if the grease is in bad shape. WD40 is a great degreaser (some people here use it as a greaser, too, but I don't like to). I've used dry lithium grease, another here recommends
TriFlow brand Superior Lubricant.
Either way, you need to open up the case and look at the rollers and bearings. If the groove where the ball rests on the rollers is 3/32"-1/8" deep or more, it's time to replace the rollers. Otherwise, it's the bearings. Once you have the bearings well greased, playing is a great way to keep the bearings rolling; you now have an excuse on having to play games.
