MacBook Pro refurbished 2011 HELP!

[Tayama17]

My MBP has been acting very weird all of the sudden and is making it unusable. I have already replaced the logic board in it about 6 months ago so I’m not very thrilled that something else is happening with it.
The problem is best described in a series of events.
I try to turn computer on and fight with it for a couple reboots with a white screen along with restarting itself.
Once I FINALY get back in, it acts normal but slightly slow.
I can be just on Safari or in my case, trying to preview my Osmo video clips to make a travel video and then the screen with go to blue verticals stripes and than put me in between screens. My curser can still move but it’s a pixel line. I’ve had that screen lasting over 2mins before it just shuts off.
I’m a freelance Cinematographer with video that’s must get done and I can’t do anything. One thing I noticed was on my left upper corner of my bottom body it was blazing hot at times. I turnerd off the MBP last night to let it sit through the night and try to open Final Cut Pro in the morning but the second the screen popped up it did the funky screen again and turned off. I did already go into the Disk Utilities and do the first aid, it says everything’s fine.
PLEASE HELP!

Need more information:

1. What exact MBP model do you have?

2. What exact Mac OS are you running? And how did you "arrive" at that OS/version? Did you just upgrade "in place", ie, have the "new" OS basically overwrite what was on your machine already?

3. Have you ever done any disk cleanup/maintenance/repairs from a software perspective? There are some excellent programs available (both free and commercial) that can help you with those tasks.

4. This is critical: are you making backups to an external device? If (hopefully) you are, what software are you using for that?

It’s the MacBook Pro “15 Late 2011 refurbishes. 2.2 GHz Intel core i7. 16GB of memory. I am running macOS Sierra version 10.12.6. My harddrive is a 1TB SATA.
For the OS I just did the normal update to it a long time ago.

I have not done any software maintained/repairs.
I do backup all of my valuables onto a 1TB and 4TB Seagate external hard drives. To get the hard drives set up I used Paragon NTFS for Mac. I’ve had this laptop for almost 4 Years now and I really want to try to make this last through college at least.

A couple of more questions/comments/suggestions:

1. The 1 TB SATA drive, is it the original one? Also, if it's an HDD, what is its' rotational speed? (If you don't know, just provide the exact model, and we can find that information for you).

2. Not doing any disk cleanup/maintenance/repairs is bad. Taking care of a Mac is just like taking care of an automobile. If one neglects to do maintenance on a car, things will get bad, and most likely lead to expensive repairs. Same with Macs.

You can actually do a lot of disk cleanup on your own. One place to look is your downloads folder (assuming that is the folder you designated with your browser and System Preferences). Also, here is some excellent free software you can use:

Onyx - Available from here: https://www.titanium-software.fr/en/onyx.html

Excellent, well-reviewed product. Has been around a long, long time. I actually depend on it (along with the excellent commercial program Tech Tool Pro to keep both of my Macs "lean, mean, and clean"). Make sure you get the correct version for Sierra, OS 10.12.6.

AppCleaner - Available from here: https://freemacsoft.net/appcleaner/

Another gem. Does a very good job of finding most files/folders, etc. for an application you want to delete.

GrandPerspective - Available from here: http://grandperspectiv.sourceforge.net/

Neat, graphical way of identifying folders/files that are taking up space on your internal drive.

Malwarebytes - Available from here: https://www.malwarebytes.com/mac/

Effective tool for finding malware/adware on your machine.

There is the distinct possibility, though, that your internal drive is "fragmented/not optimized". That can result from neglected maintenance, along with reading and writing to the drive. Unfortunately, you would need a more robust program (like Tech Tool Pro) to de-fragment/optimize the drive.

You can use Disk Utility to do some effective checking/maintenance, but it is necessary to boot your Mac via the (hidden) Recovery HD partition and use Disk Utility there to effectively analyze the drive. This link describes the Recovery HD partition:

3. Why are you using the Paragon software? That is for drives that are Windows formatted. Also, you never said what Mac backup software you are using. The Mac OS includes Time Machine, but either SuperDuper! (https://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html) or Carbon Copy Cloner (https://bombich.com/) is better.

4. What third party software are you using? And have you kept up to date with such products?

As much as I would love to just answer your questions; would erasing the disk be the best solution? I’m on very borrowed time. I can’t even get into my desktop right now to give you any of that info.

That's difficult to say, as it is critical to have a grasp on the condition of the internal drive. Also, you will lose everything on it after you erase it (especially since you do not have a backup).
