My macbook has been shutting down randomly during the past week. I wasn't sure what it was, but searched on macrumours which seemed to imply that it was probably a bad case of RAM. So I decide to run memtest, and sure enough, my notebook has been shutting down whenever I try to run it (I take it this is a sign of bad ram?) I bought this RAM 6 months ago and it has a "lifetime warranty," from G.Skill. Has anyone ever dealt G.Skill ram going bad? More importantly tho, is it bad to continue using bad ram on my Macbook? I need my computer for school the next two weeks for college, but my stock macram is back home.
