I've never had luck with kingston memory...especially their value ram. So I would try one stick of something else in slot 3. Make sure the 12V 4 pin connector is plugged in on mobo. You also may have had an esd or other problem and hurt your mobo when you put in a new bios or even put the chip in backwards... surprised at that since you never mentioned trying to flash. I disagree with bios updates helping when you can't get easyflash to work since usually its psu or ram related it might help but I have my doubts since even 1.007 (not sure about before) allowed one to enter bios and change ht speed. It may also be a short so you should try to build it outside the case. Also when you clear the cmos try to remove the battery as well as move the jumper.
