Sporadic freezing / failing to boot
Well, it's just as the title says. I'm running 12.10, and honestly I'm stumped as to what my problem is.
Sometimes my computer will fail to boot multiple times in a row, then all the sudden work great. Usually during the failed boots I get an error message "grub: out of disk", and I have to turn off the computer. Sometimes, I get that same message, and it will boot fine until the desktop loads, then everything will freeze except the mouse pointer. After a couple tries, it will work just fine (I'm posting this on it right now!).
Usually the only time it will freeze after a successful boot is when I'm playing around with large files, such as unzipping games or launching a VM. Rather than that, it doesn't freeze unless I get an error message while booting. When it does freeze, everything but the mouse pointer will be unresponsive, but I can still use ctrl alt f1-6 to get to a console, but my default x server is unresponsive and will not respond until I restart. Usually, when it does freeze up, I get the above error message while booting and it takes a couple restarts to get up and running again.
It can go days without having a hiccup or it can have a day where it takes 10 restarts for it to actually boot.
Any and all help is greatly appreciated.
