Hi everyone,
As of about a week ago, I've been having an issue where my system will not shut down. It proceeds to, but then a few seconds after the fans shut off, it reboots. I have gone through any Windows settings that could be causing the problem. Disabling/Enabling fast startup in power settings didn't make any difference. I can put the computer to sleep, and manually restart it no problem, it just will not shut down. I have to resort to throwing the switch on the PSU.
I've done extensive troubleshooting, and have narrowed it down to some sort of prob with the board itself. At the risk of boring everyone, I'll run down what I've all done. To start off, I wanted to eliminate any possibility that my problem is Windows related, I disconnected all drives, and loaded Linux onto a new SSD I purchased for my wifes system. Installation, bootup, and running Linux was all fine. Until that is, attempting to shutdown. Exact same problem occurs. Linux will proceed to shutdown, but then immediately restart. Thinking perhaps my bios got corrupted somehow, I re-flashed latest bios, loaded optimized defaults, but again no change. Close examination of the board revealed no bad capacitors or any other obvious damage. My 3770k has been sitting happily in it's socket for years, but figured I would inspect for bent pins anyway. Chip and socket look fine. To go a step further, I threw in another (known working) 3770k in it's place, no change. Still restarts on it's own. I then tried different ram, and loading one stick at at time, then testing, to see if a particular dim slot was bad. No problems there, ram and dim slots appear to be fine. I also swapped out power supplies, again no change. Now with the board completely out of the chassis and on top of the motherboard box, I disconnected everything. All USB headers, audio, and front panel connectors. So it is now just the board, cpu, and one stick of ram, in the designated spot for 1 dimm usage, and a fresh installation of Windows. This time, opting to use a WD mechanical hard drive. Once again no change. This is beyond anything I can diagnose. My skills are very limited.
Finally, I spent about 45 minutes on the phone with an ASUS tech rep, who determined the board is just bad, and warrants replacement. Problem is, ASUS doesn't stock z77 boards anymore, or at least not my Maximus V Gene. So a cross shipment RMA is not possible, and if the board is not repairable, they would send me a similar z77 board, but not necessarily an ROG board. I have two months left, of the 3 year warranty.
Would greatly appreciate any insight you might have. Thank you.My specs:ASUS Maximus V Gene (Z77)
