ASUS RAMPAGE IV EXTREME wont power up now !

Hi,

Here is my computer spec:

(1) Asus Rampage iv extreme
(2) corsair dominator 64gb ram
(3) seasonic 1250w
(4) dual gtx690 cards.
(5) i7-3930k

cooling: Ram, cpu, motherboard, gpu waterblocks, etc..

build the system about 6 months ago. i first test my system on my testbench to check everything was working properly, overclocked the system to 4.5ghz and ran a wide range of stability test softwares. The system was working and stable. Next came the waterblocks installation on cpu, ram, gpu and motherboard in the switch 810 case. power up the system when the loop was filled and sytem was running flawlessly for two months before i was posted overseas for three months. before i left, i shut down the system and moved it from my study room to my bedroom and left it there. after i came back from my overseas posting, the system wont power up anymore. however, the start and reset and bios led lights are on. suspecting the psu might be at fault, i took out the 24pin cable and tested it with a psu lcd tester. the psu fired up fine and ran my radiator fans, and pumps and fan controller etc and the voltage readings on the tester are fine. this ruled out the psu is faulty. google the web and found that some have experienced the same issue as me and solved it by changing the cmos battery. bought a new cmos battery, but no go. The system just wont power up at all, no diagnostic codes displayed, fans wont turned at all. Had a spare new seasonic 1250w psu and tried it, still it wont power up. decided to do bios flashback to the latest version by copying the bios file and renamed it to R4E.cap to fat32 formatted usb drive, slot it into the white USB port and pressed the rog connect button until it flashes. it flashes about 5 times and it stops. The asus bios flashback method fails to complete.


is my board dead ? i cant do an RMA as i have lost the stock chipset and vrm cooling block. it was working flawlessly before i left for my overseas posting. the only thing i have done to it is i had it moved to my bedroom. Can anyone out here suggest anything else that i can do to revive it before i tear down my water loops and blocks and test the board outside the case on my testbench. there is no leakage after careful visual inspection that might cause a short.

Check all power cables are secure. Try using the other BIOS chip and see if you get a POST code on the hex display onboard.

Yes. I have checked all power cables are secure and switch to bios 2, but still no go. It just wont power up even though the START, RESET and BIOS led lights up. I could see the led on my mouse and keyboard lights for a second the moment I turn on the PSU. The board is receiving power, but just wont power up. Tried to short the motherboard pins to power it up instead of pressing the START button, but no response at all, as if it is in deep 'sleep' mode. Just wondering what is causing this. It was working fine for 2-3 months before my overseas posting. Powered it down normally the night before I left and had it moved to my bedroom desk from my study room and left it there for 3 months. Anymore suggestions to revive it before I had to take apart the watercooling loop and blocks and test it outside the case, which is quite a chore. Another thing is that it will not successfully do a BIOS flashback. Looks very much the board is bricked while it is being moved from my study room to my bedroom desk. Or is it shorted somewhere preventing to power on, no Q codes whatsoever.

I fthe BIOS is already up to date it may not perform a fulll update - not sure on that. You might want to try a different USB flash drive.

If none of that works you'll have to try an RMA.

Tried two USB drives, but still no go. BIOS Flashback does not work. The light on the ROG Connect button flashes about five times and then stop.
The problem now is that I have lost the stock chipset and vrm cooling block that came installed with the R4E board after installing EK Motherboard waterblocks. I dont think ASUS will accept my RMA. Well I will just have to tear down my system in a day or two and make a final test outside the case to see if it works. If it doesn't, I will have to get a new board.
