Ubuntu 12.04 Desktop
The system randomly bumps up almost to 100% cpu use and momentarily freezes. Screen goes dim and unresponsive for a few seconds while browsing in Firefox.
Is this a hardware problem, a Ubuntu 12.04 problem or a Firefox problem?
My system is older and I've been using Ubuntu since v. 9.04. I'm not a newbie, but I only learn what I need for my uses.
I'm running AMD Phenom 9850 64 bit with 4 GB ram
This happens at different sites and times. It doesn't last long - a few seconds, and when I have 1 or more apps running. This is a new problem, but is happening more frequently. It also is taking longer to start when recovering after screen lock.
So, I don't know what to do. Any ideas?
