http://ubuntuforums.org – I have new computer with MSI 970A-G46 AMD 9 Series AM3+ Motherboard and AMD FX-8120 3.10 GHz Eight Core AM3+ Unlocked CPU with 8GB DDR3 RAM. I installed Ubuntu 12.04 on it and it is the only OS. Within days after installing, all of my applications began crashing - Firefox, Thunderbird, GIMP, etc. I had to restart the applications each time. (Hardware)
