Macbook Pro Freezing

[Tclare]

Hey,

I have a C2D 2.26 GHz 13 inch Macbook Pro running 10.8.2. I installed 8GB of RAM and a SSD about a year ago. The machine itself is about 3 years old. In the last couple of days my machine has started freeze about once every hour. Each time it does this I have to force shut down the computer and restart it to resolve the issue. I thought the issue was a software one and so last night I reinstalled 10.8.2. However, this morning the problem is still occuring. The freezing is not application specific. Does anybody know what the issue could be and if there is anyway I could resolve it without taking it into the store?

Many Thanks,

Thomas.

If you still have the original RAM you could try to install it and see if the problem is gone.

But, before you do I suggest running Apple Hardware Test, hold D on startup.

You also might try to reset the SMC.

Hi I was wondering when did you install Mountain Lion?

When it came out. I'll try performing a Hardware Test. The RAM is still registering as being in place on 'About This Mac.' Could it be a HD issue? Does spinning wheel not usually refer to that?

Hey I know it's kinda late... but I think I know what the problem is.

Is your SSD made by Crucial? It sounds like the SSD firmware needs to be updated. The freeze happens due to a bug in the original firmware, which would be triggered when the usage counter hits 5200 hours.

I downloaded the firmware update from Crucial website, converted the iso file to a dmg file, burned it to a CD, and booted from the CD. Then the update utility took care of the rest. Hope this works!

I have a Kingston V200 (I guess) that I installed in and Atom netbook and it has a similar behavior. I would take a look in the SSD... check if it has built-in garbage collection or you'll have to enable TRIM in OSX.
