Every once in a while my computer will just freeze. I can move the mouse, but clicking on anything is useless, and any window that I try to interact with will revert to "Not Responding". During this freeze, the HD Activity light is on the entire time. After a minute or two, it will unfreeze and I can just pick up where I left off.
This will happen more often as the days go by. It starts off to be once every few days, then daily, then a few times a day, then every couple minutes. If I switch my 2 memory sticks to the other slots, it "resets" this sequence and I'll get a day or two of peaceful computing. Removing the motherboard battery then reinstalling it also seems to do the trick. However, I'd like to get a permanent fix. From my temp fixes, I'm guessing either a mobo or memory problem, but I'd like to pick someone's brain and see if anyone knows some specifics about this kind of problem and how to fix it.
