It sounds like you have switched the RAM around a lot but I can't help but think the RAM isn't making good contact in the slots. I prefer to leave the RAM in when cleaning as you can get dust in the slots during the cleaning process.
yeah one slot i can understand but not 2 i have cleaned the slots time and time again with no joy i have reset cmos ,updated bios cant think of what elses i can do
can of the air stuff and a fine soft little brush it just seems funny that its channels 2 and 4 are the connected in any way is there something on mobo that controls these 2 channels could i have knoced something on mobo i just dont know i do know it cant be the ram as it bots fine in slots 1 and 3
