CPU Issue

Currently I have been having issues with my 2010 MBP. Within about the last month or so I have installed a 120 GB SSD and upgraded to 8gb of ram, which all seemed to be working great. Last week or so, it has taken my MBP anwhere from 15-45 minutes to boot up, it is fairly slow when in use, according to istat menu, my kernal_task is using about 130% CPU and when running nova bench my cpu score used to be in the 400's and now is in the lower 100's. Can anyone possibly help me diagnose the situation and possibly instruct me on how to fix this issue because I am no longer under warranty.

 

Yes, I have restarted recently, a few times actually and the same problem has occurred, but I have not tried a smc reset. I will try that and get back to you.

----------

When trying to shutdown my computer, an error message came up that stated that I could not shut down my computer because there was an error. It attempted to shut down for about 10 minutes before that error occurred. I will keep trying to accomplish the reset.



Just completed the reset and Kernel is still running at about 110% and system took 17 minutes to boot up

Also when my MBP will go to sleep, when i try to wake it, the system instantly reboots

 

I will check it out! I will put everything back like it used to be and see if I make any progress.

 

so far no such luck
