Q: Sporadic crashes/kernel panics after switching to new mac

Hey everyone I'm really hoping that someone here can help me with a problem I've been having

 

 

In late December I accidentally water damaged my 2011 13' MacBook Pro, resulting in loss of keyboard function, however the computer was still workable. And I made do until the beginning  of March when I bought a second hand 2012 13' 2.5GHz MacBook Pro. 

 

I put the ram and harddrive from my old MacBook into the new one, and everything worked fine....for the first 5  days

 

However I began to experience crashes(kernel panics?) where any number of things would happen...

 

Most commonly the computer would freeze,  briefly followed by an immediate reboot, followed by a error message saying something like "your computer restarted because of a problem"(after logging in)

 

It also presents as the computer freezing, with the sudden appearance of scattered purple/blue lines, and I am forced to hard reset. This is followed by the same error message as before.

 

I have also encountered problems with the computer not responding after being put to sleep(however this may have been fixed when I reset the SMC, hasn't happened for a while).

 

 

Does anyone have any suggestions as to things I could check or possible causes of this? Cause I have no clue.....

 

 

These problems have happened under all sorts of different conditions different,  work loads, ect.

I Also can't find anything difinitive in the console in regarded to any specific crash, and there's nothing consistent between them.

 

 

 

Things I have done:

-Reset PRAM/NVRAM

-Reset SMC

-Repaired disk permissions

-Ran apple diagnostics

-Stress tested processor using "yes" command

-Tested ram with memtest

 

 

Any thought you have would be greatly appreciated!
