been having a bit of a nightmare lately with my MBP (mid 2008) the last couple of days it has been crashing out of nowhere. not even a beach ball. the mouse and keyboard freeze, cant do cmd alt esc. also the airport just switches off and i cant turn it back on i have to restart the whole thing to get it to work again. it got even worse. restarted it but wouldnt boot up properly. i had to restart several times to get it to work. bit strange as it goes from working perfectly to being really awful now. took my mac into the apple store. they had a look at it, it wouldnt crash when i took it in. they did a hardware test which said everything was fine. they did stress tests on the cpu and it was fine. typical they cleared a load of cache and stuff on the mac and i will have to see if that has fixed the problem. they couldnt figure out why the airport wouldnt turn on without actually seeing it happen also took in my exploded battery in the hope they would replace it. nope a few days on now and its still crashing for no reason. im watching activity monitor to see what it could be and i dont see anything pushing the cpu too hard. the airport goes off and even disappears. in system profiler is says airport is not installed. i have to restart several times in order for airport to work again. and now it wont charge. i hope this wont cost too much to repair. otherwise i might just get a new one any ideas how much apple repairs usually cost?
