Mac OS X constantly freezing
My Mac OS X keeps freezing once I try to do anything. I can turn on my laptop with no problems just a bit slow, but once I try to click on anything the spinning wheel appears and stays till I have to force quit. Ive ran the hard ware test and it detected no problems? I cant run any updates on operating systems as was suggested by a friend as it freezes once I try to click on the apple icon. I dont know for sure how much memory I have left and I can't check now but I think it wasnt much. Dont know what to do....appreciate any suggestions.
MacBook, Mac OS X (10.5.2)
