Macbook Pro Stalling and Freezing not Crashing, Please help.

Question

My Macbook Pro 13inch mid 2012, keeps freezing and stalling. Google chrome keeps crashing and when visiting the likes of facebook, but I&#x27;m now using safari and its still freezing. I ran some diagnostics and it didnt come up with anything. I ran the hardware test at startup and nothing came up. I&#x27;m a college student and I&#x27;ve so much work to do so this hasn&#x27;t came at an ideal time at all haven&#x27;t got lots of money to spend fixing it so pretty worried. I also ran a Etre Scan and these are the results, if someone could please advise me I would be extremely grateful.Problem description:Macbook pro 13 inch Mid 2012. Keeps slowing down and is freezing.

When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.   These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.Launch the Console application in any of the following ways:☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.☞ Open LaunchPad and start typing the name.The title of the Console window should be All Messages. If it isn&#x27;t, select          SYSTEM LOG QUERIES ▹ All Messagesfrom the log list on the left. If you don&#x27;t see that list, select          View ▹ Show Log Listfrom the menu bar at the top of the screen.Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.Please don&#x27;t indiscriminately dump thousands of lines from the log into this discussion.Please don&#x27;t post screenshots of log messages—post the text.Some private information, such as your name, may appear in the log. Anonymize before posting.

The startup drive is failing, or there is some other internal hardware fault.Back up all data on the drive immediately if you don&#x27;t already have a current backup. There are ways to back up a computer that isn&#x27;t fully functional—ask if you need guidance.Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.Keeping your confidential data secure during hardware repairApple also recommends that you deauthorize a device in the iTunes Store before having it serviced.*An SSD doesn&#x27;t need to be zeroed.
