Laptop is now rebooting normally with a secondary drive installed. It seems the motherboard replacement fixed the problem.

I'll update in about a week with v2.

UPDATE: Installed a new Samsung 860 evo and laptop exhibited the same behavior (failure to post). Then a day later the laptop stopped powering on altogether. I returned the laptop to Asus for RMA....

The drive in question is not an OEM drive and was added by me using a sata to ribbon adapter that came included with the laptop for the purpose of the end user adding a drive to the open bay.

As far as I can tell beep codes arent a feature of this laptop.

Thank you for finding that in the log! I'll be able to test further with a new drive at a later date, if the issue is gone I'll...

I don't have anything on it that I can't replace. I'll get a new drive in the next few days. I really appreciate your help and patience! I think this mystery is solved as a hardware failure.

Boot drive is listed as "Good 100%", no warnings, no errors. 72 "unsafe" shutdowns. Probably from holding the power button to restart :|

Secondary drive is yellow "Caution". 100 reallocated...

The laptop came with a SATA to ribbon adapter that I used for the drive.

I'll run program from the link now. How can I upload the power diagnostics? Seems the forum won't allow .html

Ok, definitely related to the secondary HDD. Without HDD, restart functions as expected. After reinstalling HDD, restart works 1 time and then not again. Tested a few times to make sure.

I...

Could it be related to the secondary HDD I installed despite it not being the boot drive? All other components are OEM, and until the OS install I referenced in my first post, I was still on the OEM...

Hadn't tried that, good call. Didn't fix it though :\

Thanks for the reply!

Ran the command to turn off hibernation. I didnt receive any feedback from command prompt but fast startup and hibernation disappeared from the power options altogether so...

I'm don't organize my thoughts well, so please bear with me.

Issue began, I THINK, with a Windows update a few months ago.

Any Windows initiated shutdown/restart results in failure to post with...

It isnt just sudden or unexpected power loss. It is any power loss at all, including proper W10 shut down and subsequent unplugging.

I've just done a fresh W10 install. I'd like to create an ISO that I can use rufus (or similar/better?) to create a bootable image from USB that I can install Windows that includes all of my...

I didn't install the inf until you suggested it. I don't see any extra options though. This monitor was first manufactured back in 2012 or 13 I think so I think the generic driver is probably the...

Installed it. Still limited to 60Hz. MonitorInfoView is reporting the same EDID version before and after regardless.

Should I bother trying a new HDMI cable? I don't mind using the DVI, this...

Yes I am using the generic driver. I see an EDID key but not EDID override.

I found an old dual DVI and plugged it in and voila 144Hz.

I'm guessing either I'm mistaken about my original set up...

Got it. Was able to delete and regen that key but with no change.

Thanks. I received an error when trying to delete the entry.218888

It shows the vertical frequency range to be 56-76 Hz. Can you clarify what you mean by delete the entry?

Right. But I removed the kvm switch.

I hope this is the correct place to post, I apologize if not.

I have a 144Hz 1080p monitor, GTX 1080Ti, connected with a HDMI 2.0 cable. When I first set up this system a little over a year ago, I...

Thanks for the reply. I had tried both of those suggestions before to no avail. I ended up reinstalling windows again anyway and now all is well.

I downloaded a new iso and started from scratch...

Some more info that may or may not be helpful:
