Why is my MacBook Pro freezing?

Question

macbook

Hello.

MacBook Pro 13 early '11, El capitan - began to freeze tightly about once an hour, only the mouse works.
It costs 60GB ssd and 320GB instead of a floppy drive, Corsair Mac Memory RAM two 8GB sticks.

I checked the SSD and HDD for errors, smart and everything that can be checked in the DiskTool Pro 3.1.9 application - everything is fine.

It’s impossible to check RAM using Rember in safe mode - it freezes, it also doesn’t work to pass the apple test hardware, it freezes around 90%.

Now I put my native RAM, it hung in the same way.

What are the options for checking and possibly resolving the issue?

Answer 1

Check your disks with Disk Utility from Mac OS. Most likely FS is damaged, DT Pro may not "see" this.

Answer 2

Is there no overheating?

Answer 3

El Capitan has been standing for a long time? Maybe roll back to the Mavericks?

Answer 4

How was everything decided in the end?
