Built a computer and when I power it on its stays powered for about 10 seconds and then powers off for a couple of seconds and powers right back on and repeats. The Dr. Debug display says 55 which means "Memory not installed." I removed one of the sticks of RAM and repower it on and the code A2 shows up which means "IDE Detect". I unplug the USB keyboard and replug it back into a USB slot on the mobo and the code "64" pops up which means "CPU DXE Initialization". Any help of where to go from here would be great.

Ok, not sure why my first answer didnt post but...I have two of these boards. I had the same thing happen and it turns out the bios chip went bad. But, I reset the bios (unplug, remove the bios battery, return the battery after a few minutes) and the pc worked again except for the PCI-e slot two. The rest of the board worked fine. I called ASRock and they sent me a new bios chip for it and it worked fine once installed (which only takes a minute to install but took a month to get it from asrock). Hope this helps.

yes..Mine was doing all that stuff. At first I thought it was my PSU..tested fine..then I thought it was one of my 660's I have in there..nope.. they both worked in PCI-e slot 1. None of them worked in PCI-e slot two. How many GPU's are you running?

Error 64, from the boards manual, is: CPU DXE initialization (CPU module specific). A few from another forum stated this..
Some of the usual things are a bad/bent contact in the CPU socket, a bad mounting of the CPU cooler (which one?) or even inadequate power to the CPU (eight pin CPU power cable connected to the board?) One guy even said he had to loosen his cooler after getting this error due to him putting it on too tight.
