Hey people. I recently bought a Macbook Pro 15 inch i5. a while ago it started to get slower. over time it slowed down very much and even started to get stuck when i was just working for about 3 minutes each time. the only thing i could do while it was stuck was move my mouse. i couldn't do anything else. it got worse and worse and worse. until it wouldn't boot up anymore. it just got stuck at the spinning wheel on the apple boot screen. i reinstalled snow leopard with the cd that came with it. i didn't format my harddisk, and when it was installed it would boot up, but it still remain as slow, and with the crashing apps. it still got stuck everytime. i erased my whole harddisk and installed snow leopard again. everything was fine. a fine new laptop. 3/4 weeks later it started to get slow again. and the whole cycle started again. it got slow, apps were crashing. i am even unable to start iphoto. i have to open skype (example) a few times before it is stable and runs without to crash. until now. it won't start up anymore and i am tired of this. i am doing the apple hardware test right now so i don't know if it is a hardware problem. i already repaired an verify'd my harddrive via disk utility on the installation disk. i don't know what to do anymore. i don't want to send it to apple anymore. ( Reason: i had a normal white macbook a few years ago and it wouldn't boot up as well after i dropped it. i send it to apple and they didn't react anymore. i had to send a letter and they just came up with a problem. the harddisk was "broken". i would cost 600 euro's to repair while if i buy a harddisk myself and build it in it would cost me only a hondred. after a while it seemed that the harddisk wasn't broken at all. i was just able to install leopard again. they lied to më. ) do you guys have an explanation for this or an idea how to solve this problem? thank you all!
