i'm having problems with my keyboard and trackpad freezing at times. Sometimes it will freeze completely, no keys working except for the power button. other times it will freeze for just a few seconds then unfreeze itself. the first scenario is esp bad because if im working on a project or typing a paper and it freezes, im SOL. sometimes it'll even freeze u when i turn it on. when the main screen comes up i cant move the mouse and the aforementioned problem starts. sometimes i have to turn it on and off 3 or 4 times before i can use it again. also, my keys sometimes "stick", and by stick i mean they will repeat itself after i've stopped touching the key. it's not literally stuck down, but it keeps putting the same letter (or doing the same function) until i push a couple more buttons. anyone have similar problems? i've tried everything i can think of. the only thing left is to reformat the hard drive. I want to use time machine afterwards but i'm afraid if its a software issue, i'll just put it back on my computer after the reformat. can anyone help me? please! i'm desperate! any help would be appreciated! my computer stats are in my signature.
