Ubuntu 12.04 was running great on a Dell Dual CPU 2.16 ghz with 2 gb ram for a couple years. Something happend within the last couple days that has made the system super slow.
I looked at the system monitor and just scrolling the mouse a little bit took both cpu's to 100%. Just typing this I'm way ahead slowly typing to the display!!
I've happily used ubuntu for several years, but I'm really a beginner when it comes to nuts and bolts of the system.
Any suggestions would be welcome!
