I recently built my first computer and installed Ubuntu 12.10 on it. I've been using Ubuntu for years, so I installed it on here two nights ago and everything was running smoothly until last night. I'm not even sure this is an Ubuntu-specific issue; it may be an error I made in constructing the computer.
In Google Chrome and Firefox (the only two applications I've noticed the error explicitly) when I'm browsing the web I'll get a black screen with an error message about a general protection fault on CPU 5 like this (https://www.dropbox.com/s/74gj6f7cmk...2016.19.49.jpg) and/or compiz closes. Usually the computer also freezes and I can't do anything except power it off and back on.
The outputs from lspci (hw.txt), /var/log/dmesg (dmesg.txt) and /var/log/syslog (syslog.txt) are attached for inspection.
If anyone could provide some insight or help guide me to figure out what's going on, I'd really appreciate it!!
