I've just replaced an old version of Ubuntu with Linux Mint 14 Nadia on this computer (dual boot with Windows XP, which I primarily use but want to slowly convert to using Linux).
However almost every time I use it, it ends up hanging/crashing.
The first couple of times it happened when I was editing the time/date format in Cinnamon settings.
The second couple of times (on consecutive days) I was using Firefox.
And yesterday it seemed to happen just after I left the computer and the screensaver (monitor shut off) activated.
The mouse cursor stops moving and after a few seconds disappears. There's no response to any keyboard or mouse input I've tried, except Alt+Sysrq+B to reboot.
There's been nothing in the syslog when it's happened, except at yesterday's crash when I saw this:

Here is my inxi output:

Am I right in thinking the above 'failed' shows that something isn't compatible with my video card, and could this be the cause of the problems?
Many thanks in advance.
