All applications crash in my 2011 Macbook Pro after a few minutes of operation
I have an early 2011 Macbook Pro that recently had a hard drive failure. I went to an Apple service provider and I got a new 500 GB drive, and did a fresh install of OS X Yosemite. Unfortunately, Safari, iTunes, the App Store, and Firefox applications will all work for a few minutes before they "quit unexpectedly" (I'm writing this on borrowed time). It was exhibiting the same type of failures before the last hard drive failed, and things got progressively worse until the entire computer no longer could start. I don't know what could be causing the problem because there were problems immediately when only default applications were installed.
Its specs are:
OSX Yosemite, 10.10.3
Processor: 2.3 GHz Intel Core i5
Memory: 4 GB 1333 MHz DDR3
Graphics: Intel HD Graphics 3000 384 MB
MacBook Pro, OS X Yosemite (10.10.3), Early 2011 Model
