In the last 3 days, my Ubuntu box got stuck about 10 times, By stuck I mean everything froze, and the only way to restart was from the button on the case.
Today it froze about 10 times, and I have been also getting the past 2 days problems restarting the computer, sometimes the POST screen wouldn't come up, so I'd restart some more, or pull the plug, leave for an hour and return. Today was the weirdest, it got stuck 2-3 times right before GRUB coming up, I suspect GRUB was the reason the PC froze.
I suspect I have a failing HD on my hands, so I opened the case, took out the HD and listened to it a bit while booting windows 7. It makes weird clanking noises, BUT I don't know how it should sound, so maybe I'm just paranoid.
Also, what's really weird about all this, is that Windows operates totally normally.
I'm really no sure what is happening to my computer. I'm backing files up just in case.
So it really comes down to: how should I stop my ubuntu from freezing, and whether I should be getting a new HD soon.
Edit: I did several scans and tests on HDTune, even checked every block of the HD for bad sectors and what not, all came back normal. Then ubuntu \ cinnamon \ removal of package 'tracker' \ other is the offender. I'm not sure where to begin looking. Also, since noon, no crashes.
