Can someone help me with this? I just setup a RB133 board, I loaded the new 3.7 O.S. I enabled the wireless card to make sure that my new equipment works. I add CPU to the (task) bar at the top of the GUI 5%, 14%, then 100% about every 3-4 seconds. I disabled the wireless card to make sure that the card wasn't affecting the CPU. I doesn't seem to matter. Like I said there is no config on the board at all. Will someone try this test and see if you get the same results. I have replaced many boards to larger boards with more memory/CPU to get away from these spikes to 100%. Low and behold a board with no config hits 100% every 2-3 seconds.
