I am ready to tear my hair out. I had my computer built in the case with everything connected. I went to turn it on for the first time, and the fans spun half a turn, and then turned off. Under the ?�ASROCK??logo (cover) there was a blinking magenta light. I rechecked all connections, unplugged power supply and plugged it back in. Next time I pressed the power button, nothing spun up, but again underneath the ASROCK logo cover there was this time a greenish light that flashed once then it switched to magenta and continued flashing. When I say flashing it?�s about every couple seconds.

After this failure, I took everything out of the case and placed the motherboard on the motherboard box. I then disconnected almost everything. I only had the CPU, RAM, power supply, and cooler connected. Cables I had connected were the 24pin MB cable, the two 4pin CPU power cables, CPU fan, and the ?�HD AUDIO??header from the case. I plugged in power again, and nothing spun up, no beeps or error codes, only a blinking magenta light under the ASROCK logo cover.

At this point I did some googling and saw people with older revisions or similar models having success removing the CMOS battery or clearing CMOS. I removed the CMOS battery and disconnected power and let it be overnight (7 hrs). I cleared CMOS by moving the jumper on the 3 pin and then moved it back. This produced the same result as before ??blinking magenta light under the ASROCK logo cover. 

I?�ve tried multiple RAM configurations. Leaving only one in, trying all the slots. No dice. My power supply came with a  ?�tester??connecter which when connected to the MB cable, the power supply fan spins right up. Also, at one point during troubleshooting I disconnected the 8pin power cable from the PSU, and turned on power switch. The fans spun up (CPU cooler + PSU), but the PSU was clicking, and the magenta light under the ASROCK logo was flashing rapidly. I assume because it was telling me I needed to plug the 8pin power cable in. I reconnected the 8pin CPU power, and back to the old result of no activity except flashing magenta light under the ASROCK logo. I also tried shorting the header to jump the board ??didn?�t do anything.

Completely at a loss. Hoping it?�s something stupid I missed. I do suspect the motherboard is the culprit. I checked the pins and they appear to be fine. I just don?�t know why it won?�t even post or do anything except flash the magenta light. The manual does not contain any information on error codes or light flashes, and neither does the ASROCK website, so I have no idea what it means.

Any help would be GREATLY appreciated!
