You want to leave C&Q enabled for the automatic CPU power savings. Only disable C6 state to not let Windows shutting down your CPU cores.
I'm aware you can change it, but by default it's at 5%. This person's experiencing crashes at idle. My train of thought is Windows may be dropping the voltage too low.
Your findings may be correct and the Ryzen Balanced Power Plan by default prevents the frequency from going below 90%, instead of 5%, thus hopefully fixing the problem.
YOU may want to leave CnQ and C6 enabled, but it's not mandatory. While troubleshooting, it's sometimes necessary to give people additional options and suggestions to try should other ideas fail.

It doesn't makes sense, but I guess if it only crashes at idle, I'm guessing Windows's default balanced power plan lowers the CPU frequency and voltage a bit too much to conserve power/reduce heat. I'm wondering if disabling Cool and Quiet, and C6 State would also stop this from crashing at idle as it'd keep the voltage from dropping so low.

Once installed, set Ryzen balanced power plan, disable USB and Pcie power savings inside the plan.

Boot to UEFI, disable CPU C6 state. Reboot and let us know how it did.

Cheers.

It seems unlikely that your memory is the problem if you can run stress tests for hours without any failures. Memory problems are also usually BSODs and do not cause the video signal to fail.

If the monitor goes blank, which does not happen for any kind of Windows failure or BSOD, I would suspect the video source. Windows 10 likes to install drivers unless you have it configured to not do so. When Windows installed video drivers, I had problems like this with the screen getting no signal.

Did you install the video driver yourself? Do you have Windows 10 configured to not install drivers? Do you still have the same video driver version installed that you installed, if you did it yourself? I had problems with my video card until I made sure that Windows 10 did not install any drivers

If the monitor goes blank, how do you know that the mouse and keyboard are not working?

I also wonder about the PSU IMO. 500W is the usual minimum for a GTX 1080, and that Corsair CX500 is a basic PSU. The Thermaltake might be 750W, but I'd like to know the model number to check the voltage rail specs.

I've seen Ryzen users say Ripjaws V DDR4 memory works fine, and other that said it doesn't. No G.SKILL model number so we don't know which type you have.

Hmm, sounds like power but couldn't be given the 2 PSUs you tested.... It is remotely possible that they both have some issue with your board but unlikely. 

The other possibility is RAM as you mentioned. If you can get your hands on some other RAM to test with (preferably from the QVL) that would help nail it down. Ryzen has proven a tricky beast for a lot of people, in the end it is worth it however. I am loving my Ryzen system Wink

It's 2am here now so I am off to bed but good luck and let us know how you fare Thumbs Up

I downloaded Windows 10 installer 3 days ago from Microsoft and installed it using a USB drives. I did all the necessary updates too.

Just to clarify, I don't get BSOD or freezing. The monitor, keyboard and mouse shut instantly and everything else keep running, just like in the video above. I have to hard reset the computer from the PSU because even holding the front power switch for 10 seconds doesn't shut the computer.

Is your windows 10 installation media a fresh download?

I had similar issues with my Taichi (random hanging then resuming) until I did a fresh install using a newly downloaded Win10 installation medium. The problem seemed to be coming from the Windows 10 anniversary update. Whenever I tried to install from my older media it would immediately give me issues once the anniversary update installed (after OS installation). By downloading a fresh install medium you get the update bundled with the install and for some reason that worked for me. I have been stable for months now with no crashes, BSODs or freezing. See my sig for my overclocks (except RAM that proved unstable over time so I am at 3200 now).

If it isn't the latest then try updating. Be sure to use the instant flash option, it is by far the safest method. Download the instant flash BIOS file from your board's product page and follow the instructions. 

You have done a great job troubleshooting so far. Let us know how the update goes (if you have not done so already).


I've already updated the bios to 3.1 using a thumb drive... It's one of the first thing I did.

Your help is welcomed :)
