Chosen Solution
Hello, my MacBook Pro is freezing randomly. First of all I tried a new EL Capitan installation and I was repairing the hardrive, too. Then I did change the memory and I did use another hard drive but the problem still persists. Also I did a PRAM reset and SMC reset, but nothing changed, Then I had the idea to boot into safe mode, in the safe mode the MacBook Pro didn’t freeze. So I did all the steps found here, but the problem still persists in the normal boot mode. Does anyone have an idea to solve the problem?
If it runs fine in Safe Mode but not with a regular boot, you have a software issue. You can get viruses off the internet or via email attachment. They have gotten very sneaky. Look in your downloads folder and question ANYTHING. Most Macs I get in nowadays are infected. Or have things like Genio or MacKeeper. To verify, reformat the drive, use the “Write Zeros” option to map out any bad blocks. Reinstall the system via a flash drive, external back up drive with a system or via an internet install and see if you problem is gone.

I am having this same issue. Did you ever find out if it was a motherboard issue?
I am in the process of checking my video card. I have a MBP mid-2009 version and my computer freezes randomly throughout the day no matter what I am doing. I’ve tried upgrading my RAM, a new hard drive, and a updated OS (Lion to Maverick). I did each “possible solution” one at a time to see if any one would fix the issue and nothing. I just read a thread that stated they blew the dust off the video card and that fixed the issue. https://discussions.apple.com/thread/204… Let me know if this helps.
