So, i bought a brand new macbook january, and it started running ultra slow (i mean reallllllllllllly slow). SO far, i have tried lots of things, from a simples permission fix to reinstaling the OS, erasing everything that was on the HD. Needless to say, nothing worked. I think it might be some problem with the hardware (my warranty expires tomorrow), so i just wanna make sure i tried everything before taking my macbook to the technical support. It all started when i suddenly removed a 3G modem from the macbook. After that, when i first tried to turn it off , it didnt. I waited like 1 hour or so and it didnt shut down. So I pressed the power button. Next time I turned it on, i had to try the command+option+p+r and shift+option+alt+power, because it wasnt going past the loading screen. After several forced reboots, it finally turned on. But it was so slow. That was 1 month ago. S.M.A.R.T. utility says my drive is failing (with over 4.000 errors), but the utility disk (app folder) says it's ok. As I said, I tried a lot of things to fix it, but i couldn't on my own, so i'm asking now the gurus for advice. What should i do? Thanks in advance.
