I am using a mid-2012 MBP 13in with no retina display, running OS X 10.8.3. Everything was fine until I was watching a video clip on Facebook. Everything just froze, except the mouse pointer can still move, but I can't do anything else. So I was forced to long press the power button to shut the machine down. After that, the whole system was ridiculously slow.

I can boot into my own account, but starting/running/closing any program takes ages. Also, when I tried to mount a .dmg. I was given a error message like "No suitable file system." I know I can just re-install the by booting into the recovery partition, but I'll take that as my last resort.

Here are more screenshots of the Activity Monitor:

Are you sure you are running 10.8.4? That would be a developer-build of a version of OS X that has not been released to the public yet. Is this the case? I believe that we do not permit questions concerning developer builds of OS X on this site. –  Wheat Williams May 5 '13 at 15:59
    
Oops, typo, should be 10.8.3. –  yihangho May 6 '13 at 3:33
    
Can you confirm - how much space left on your system partition. Maybe in "Disk Utility" run a full disk check. And "repair permissions" while you are at it. –  bdecaf May 6 '13 at 13:49
    
@bdecaf Well, I've just reinstalled the whole system. But I am sure that I have used less than 100GB for the system partition. (It is about 400GB in total for that partition.) –  yihangho May 7 '13 at 14:42

It turns out to be a hardware problem. After getting frustrated with the extremely slow response, I reinstalled OS X via the recovery tool. But that doesn't last long - it starts to get slower (but not as slow as this case), and the Disk Utility complains that "This drive has a hardware problem that can't be repaired." So I send my MacBook back to Apple and they replace the hard-drive for me and it was covered by warranty.

Check Activity Monitor for what processes maybe slowing the system down. Be sure to switch from "My Processes" to "All Processes" at the top of the Activity Monitor window.

Frankly, I can't even get to Activity Monitor. I tried to look for it using Spotlight, but it took too long to return a result. –  yihangho May 5 '13 at 16:45
    
Maybe try to safe boot first (hold Shift during boot). –  zac May 5 '13 at 16:54
    
I've added screenshots. Please take a look and advice. Thanks. –  yihangho May 6 '13 at 4:15
