Macbook pro freezes constantly -HELP
Please please help. It's driving me nuts. My macbook pro early 2011 started freezing, with lines on the screen and I am have to force shut down evertime.
It first started happening about a month ago, like 3 times in a row in one hour, then I followed a series of procedures that I found here in the forums and stoped, then since yesterday started happening again, and the computer doesn't last more than 10 min without freezing. without doing anything in particular, like just using chrome.
I have started up in safe-mode, I have used disk utility etc.
Note: I installed 2 new memories of 8GB each..could it be this?
Can anyone suggest anything before I have to take it to an apple store? I live in Rio de Janeiro and they take 15 days just to inspect the computer! I can't be this long without computer!!
Many thanks in advance
MacBook Pro, Memory 16GB 1333 MHz DDR3
