Hi Folks, I'm not sure what to do at this point. My 2010 15" i7 started beachballing more, followed by garbled video, black screen, random shutdown and eventually the three beeps signifying something is up with the RAM. I took it in to my local Apple Authorized Service Provider because eventually it wouldn't even start up. They sent it off to Apple who replaced the RAM. It came back to me, and six days later it is doing it again. However, when I took it back in, it did manage to start up normally. They took it in to their repair depot, and a few days later told me to wipe it, and reinstall the OS. I did so even though I'm pretty sure it is not a software issue. I plan on taking it to them again tomorrow. Any suggestions? By the way, I ran the Apple Hardware Test, and it won't even finish.
