I've seen a hundred threads like this popping up all over every search engine, yet nothing solves my particular problem. So here's my short story.

Recently my chassis started leaking in the liquid cooling system for the processor. Since I still had warranty, I turned it in to where I bought almost all the parts. They checked it out, found that the Graphics card and motherboard where damaged, the rest of the parts were unscathed, which seemed likely from what I could guess myself.

Now, two months later, I put together my computer again with a replaced graphics card and motherboard. Pretty much the same setup as before, similar motherboard and graphics card.

When I am done, I plug the computer in and try to power it on, and it does not power on. Instantly I think it might be something with the power switch cables, so I try the on-board power button on the motherboard. It did not work either. I look over pretty much everything I can think of. Eventually I press the clear cmos button and the computer boots. Fantastic. I check the BIOS setting quickly, boot order is fine. Memory is all there. The only slightly strange thing is that it says there's no card in PCIe port 1, which is where my graphics card is and my monitors are connected to.

Either way I save and exit and the computer shuts off very suddenly and doesn't power on with any buttons again, except for the clear cmos button. After various internet searches, I first try to update the BIOS, which was successful but yielded no results. I eventually try starting the computer, going into bios and then exiting and discarding changes. It worked. Now the OS starts up, I log into my Microsoft account and all seems well. I check memory, CPU and my GPU. Even tried running a game and it works fine, 160 fps at War Thunder with full graphics settings on.

I try rebooting the PC, it worked. I try shutting it down. Back to square one. Start up again with clear cmos, discard changes, Windows boots all is well. Computer runs like usual. Check the Q-code display on the motherboard and it's "AA" meaning that all is well and the OS is now handling the rest.

I can't detect any problems as of yet, just that annoyingly I have to start the PC in this manner every time it shuts off for any reason.

The motherboard and graphics card are completely new, replaced and the computer worked the last time I used it without the leak of course.

So, after all of this. What is the issue and how do I solve it? I am going to call the company that "repaired" my computer and ask them about it, but I doubt it will go anywhere. As I said, nothing wrong so far and I am in fact typing this post from the computer in question.

Specifications:
GPU: Gigabyte AORUS GeForce GTX 1080 (replaced from ZOTAC GeForce GTX 1080 AMP Extreme)
CPU: Intel i7-6850K 3.6 GHz
MB: ASUS X99 Deluxe II (replaced from MSI X99A XPOWER GAMING TITANIUM)
RAM: Corsair 64GB (4x16GB) DDR4 3000MHz CL1 (all accounted for)
PSU: be quiet! Dark Power Pro 11 1000
Chassis: Deep cool Gamer Storm Genome II

Drives:
OCZ RD400 512GB M.2
OCZ TR150 960GB
WD Red 4TB IntelliPower 64MB

Any help will be appreciated greatly. Hopefully, even though the warranty ran out during their extremely lengthy repairs, if anything is damaged in any way I can get a replacement.

Thanks beforehand,
David N.
 
Check your BIOS setting for what video card you have set for it to use. Also it is troubling that it doesn't pop up in BIOS.

I have an ASUS x99 deluxe II as well. It is the buggiest POS motherboard I have owned in the past 20+ years. I bought an MSI to replace it (not yet installed because I am over-worked and a little busy with kids and stuff at home). I only mention this because it "might" be another QA problem from Asus. In my case I could not install on the SSD until I removed all other drives. I could then install on the drive I wanted. It took me multiple tries to get it to accept my ram (Corsair lpx 3200 64gb). It complained every boot that I was overclocking too high (was running it stock).

A bios flash helped the OC issues when I was not OCing. Nothing resolved the issue with not liking SSDs unless I forced it (as above).

Have you tried flashing the BIOS? If I were to guess, this is where the issue resides for you (based on the problem you describe and that clearing the bios allows a 1 time boot).
 


That does not sound good, maybe I can get another motherboard from the company that replaced it... if they will allow that, probably not.

So you don't know how to permanently solve this then? That is unfortunate. I did update the bios to the newest version, 1702 I think. It did not alleviate my problems.
 


Sorry no. I went round and round with my own Asus x99 problems until I reached the point where I swore off Asus.
 


Considering your story, and now my own problems. I think I might also never use Asus for motherboards again. They make some other nice things, but this is my first Asus motherboard and it's causing so much grief.

I have contacted the company who replaced my parts, and I will deliver my motherboard and CPU to them for testing and they said they will replace the motherboard (again). Hopefully it doesn't take two months again, but they assured me it would not.

Other than the motherboard acting spooky, the PC works perfectly and I can run games on it, and indeed, browse the internet and type here. Which makes me fairly certain that none of my components are damaged.
