OS X Freezes on Disk or CPU usage on Niresh Mavericks 10.9 + Update 10.9.5

[johnburn]

Hi everyone,

 

I'm having a weird issue, when I do certain tasks the OS freezes and becomes unresponsive, at that point the only way to "fix" that is force shutdown pressing the power button from laptop.

 

The only two ways I reproduce that are:

1. Using Box Sync, when that program starts syncing after a while (not to much) the OS hangs
2. At first boot when OS restores opened programs and Google Chrome has a few tabs (like around, I don't know, 30 for example), Chrome starts restoring every tab and OS hangs after a little bit (while restoring tabs)

Anybody experienced this or have any ideas about it?

Thanks in advance.
