Mid 2010 Macbook Pro suddenly haywire.

My 2010 MBP which although slowing down has been faithful up till now recently become dysfunctional following a series of forced reboots.

Memory pressure is low with little more than half the physical memory used and the CPU's idle load rarely drops below 80% .

Yet (regardless of the number of apps and/or windows open) applications sporadically fail to respond, effectively freezing the computer momentarily.

When this happens besides showing the affected application/process in red the Activity Monitor itself bogs down ; read/write both drop to 0/per sec. and pinwheels abound.

I have been running Yosemite on this machine for about three months without any problem.

I have used the info on similar threads to painstakingly root out malware (there was one present though it's removal showed no improvement.)

I have also used disk utility to verify and repair where applicable (including permissions)

I don't know where to go from here did I break it ? Any help would be greatly appreciated.

MacBook Pro (13-inch Mid 2010), OS X Yosemite (10.10.3)

The problem is likely due to the discrete GPU failing. Download gfxCardStatus 2.3 and use it to disable the discrete GPU. This is a temporary workaround until you get your motherboard replaced.

When you see a beachball cursor or the machine is unresponsive, 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't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from 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't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.
