Hey guys, it's been a while since I've been on this forum so not sure where to post. I bought a 13" i5 ivy bridge mbp with 4gb ram last week after being stuck with a PC for the past 2 years. I've been considering going back and having them install 8gb ram, BUT this past week the computer has froze and restarted twice while running the combination of playing music on iTunes and syncing iPhoto. This doesn't seem very hard core to me but the computer has had a hard time. Today I got what used to be the grey screen of death (Your computer needs to restart) while just checking my email. Is this common (cant remember, I haven't owned a Mac since leopard) or should I just go and insist on them giving me a new model? THANKS!
