I have a 2010, I believe MacBook Pro 15 inch.
Build is 11D50b
Processor 2.4 GHz Intel Core i5
Memory 8 GB 1067 MHz DDR3
Running Mac OS X
Version 10.7.3

I upgraded my harddrive in Nov 2011 to 1 TB.
I have 222 GB on this.

I upgraded the memory from 4GB to 8GB at the same time.

I have started in the last month having problems with it locking up.
I have taken any movies and such off this harddrive. I do have some projects.

I now am having problems with it taking forever to start up and anytime I try to do anything the beachball spins forever...

I rebooted at 9:29 AM
it was up at 10:08 AM

That is crazy!!!

Is there anything less than reformating that I can do?
Please advise.
