This is the rig I built a few years ago. It has a Gigabyte mobo but it hasn't been changed yet. I was planning on it but family issues moved that from a burner to not even on the stove and cold as ice. This issue just sort of popped up out of the blue. Also, I'm using the same kernel I been using for a while now. 3.9.5-gentoo I been using that kernel since the middle of June. I have tested newer ones but ran into other issues, nvidia mostly. My keyboard/mouse is very old school. PS/2. :-D Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words!
