Let's start over, because, and I appologize, in that picture I honestly could not tell that you had memory in those slots. So, here's what you want to do.
I now see why Calvin was telling you that memory compatibility is only guaranteed in the form in which it is sold, and what he means by that is that on any given motherboard, and it can change from one board to the next even if they are the exact same motherboard, when you mix ANY memory there is always a chance that it will not play nice together. Obviously, you have two entirely different memory kits installed. I was only seeing one kit in that picture. I don't know why I didn't notice there were DIMMs in all four slots.
@Calvin7 , I appologize. Had I realized there were two separate kits installed I would have understood your post was appropriate and that's my fault. Obviously YOU saw that there were two kits, while I did not.
So, this is what you should do to try and get them to work correctly and hopefully they WILL play nice together.
The DIMMs without heatsinks on them that are currently in the 1st and 2nd slots. Move the DIMM in the 2nd slot to the 3rd slot. Move the DIMM in the 3rd slot to the second slot. Do that with the power disconnected from the PSU or the wall. Next, remove the CMOS battery for five minutes. Next, reinstall the CMOS battery and reconnect power. Then, power on the system, go into the BIOS, find the option to load the Default or Optimal default settings and do so. Save setttings and exit BIOS. Power off. Power on and see if the system will POST. If it will POST, good, see if it will boot to Windows. If it does, then run CPU-Z and check to see how much memory is showing as installed and available on the memory tab and whether or not it indicates dual or single in the channel field.
