My MacBook Pro is restarting randomly and runs slow. What can I do?
Good evening, I have this MacBook Pro (15-inch, Mid 2010), it has modifications because I bought it online on Apple.com, it has a 2.8 GHz Intel Core i7 and 8GB 1067 MHz DDR3, and it's running on - MAC OS X MOUNTAIN LION 10.8.2 - so... Since 1 month thru here, it began to run very, very slow without any reason, and last week it began to restart randomly when I'm using it, last days restarts were more frecuent, also I discovered that when I open Quicktime, it restarts inmediatelly, but it restarts anyway if I don't open it, the only difference is that it's not inmediatelly. Today it has restarted like 5 times, twice in morning and 3 times in secuence in last 30 mins. so I'm very worried about this, I found on this Apple Support Community something about the Spotlight bla bla... I did it and it still with the problem, I called Apple and they said that if I pay 50$ they can assist me but they can't say if the problem will be solved. So please, I ask to you people of this community to help me in this, I'm studying right now and I need, NEED this computer to work, also I have all my works here! I'm gonna backup them, but I need this to work. Thanks for the help and time. Sorry for this bad grammar, not english speaker.
