Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

I realise I made the wrong call by posting this issue to that annoying place called Reddit 6 months ago, so I'm posting it again here where it belongs.

Hi.

I've made this topic because I've discovered I have an issue which has terrible coverage online and no single hub of discussion. I only discovered its cause 7 months after I first had it, because it was notoriously difficult to reproduce.

According to my research, this issue affects AMD CPUs (at least Ryzen, FX and Phenom). Motherboard doesn't matter, Windows version doesn't matter, graphics card doesn't matter, RAM doesn't matter.

Issue:

At random times, the monitor(s) will cut to a black screen (no signal), and fans will immediately speed up to default-default settings (pre-POST). Power continues to be supplied (including to peripherals), but nothing will work, not even the power button or reset switch, forcing you to switch off the PSU or mains power and switch it on again. For me, half the time, the PC would automatically reboot after the blackscreen, exactly mimicking the effect of the reset button (though I ruled out the reset button as a cause by unplugging it). I did not have any BSODs or minidumps. There was nothing about it in my Event Viewer either.

The frequency of the issue is very unpredictable, but it started immediately after I built my computer. It happened to me on the following dates (I kept a manual log):

  • 31 August 2018 and 2, 10, 17, 18 September 2018

  • 8, 9, 10 February 2019

  • 8, 9, 10, 13, 14, 15 March 2019

HWiNFO logs leading up to the crashes in March showed nothing out of the ordinary, even in the last second before blackscreen. Stress testing in Prime95 and Superposition could not induce the issue. On one day in September, the computer even woke up from sleep straight into this black screen state.

Cause:

I noticed during March that the problem was occurring when I had HWiNFO, MSI Afterburner and ASUS AI Suite open at the same time. I then managed to confirm online that the cause of the issue was some sort of conflict involving multiple hardware-monitoring softwares running. Sources specifically point to a CPU thermal sensor issue.

I was not monitoring the HWiNFO ASUS sensors which prompt a warning of instability in March. Also, the problem previously occurred when I had CPU-Z, CoreTemp or Speccy running instead of HWiNFO. The problem may also have happened when only AI Suite and Afterburner were running. Other users online report the issue with various other programs that monitor sensors.

Fix:

The workaround will be obvious – to avoid using multiple programs that could monitor the CPU temp sensor. But I've seen no information about a fix or the issue being resolved by AMD themselves. There are hints in some of the topics below that BIOS or driver updates have reduced the symptoms, but the only surefire way I know of to avoid this issue is to avoid running multiple hardware-monitoring processes (in my case, more than 2, it seems).

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

As usual this is a self inflicted problem and definitely NOT an AMD problem.  Running junk-ware from MB and other vendors will ultimately be bad news and running multiple ones even more sever problems.  In the case of Ryzen, users should ONLY run Ryzen Master.  Enjoy, John.

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

It's an AMD problem because the only commonality I've seen across every online post that suffers this exact problem is an AMD processor. Also, Ryzen Master is irrelevant, because if you'll check the links I included, Ryzen Master (and AMD Overdrive for that matter) was one of the triggers for the crash, and the problem affects FX and Phenom processors too, at least. You seem to have a history of insisting users use Ryzen Master or screenshot Ryzen Master before helping them. At least read the featured links before wrongly assuming the problem is self-inflicted – the ROG post and others confirm it to be an AMD CPU temp sensor issue, and Intel doesn't seem to behave this way.

I've been running MSI Afterburner and ASUS AI Suite constantly without any issue since the last crashes. Only when I launched a third CPU temp monitoring program like HWiNFO, Speccy or CoreTemp did the computer blackscreen after a few minutes.

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

Before asking a question the forum headers asks you to provide your system information. I don't really have enough information to offer a suggestion so please give the following information as required to post:

When posting a new question, please provide as much detail as possible describing your issue making sure to include the relevant hardware and software configuration. 
For example:

  • Issue Description: [Describe your issue in detail here]
  • Hardware: [Describe the make and model of your: Graphics Card, CPU, Motherboard, RAM, PSU, Display(s), etc.]
  • Software: [Describe version or release date of your: Operating System, Game/Application, Drivers, etc.]

That being said what you describe sounds more like a power issue and likely affecting GPU not CPU. Once we have specs we can give a better idea of what to try.

As already mentioned AMD does not suggest the use of 3rd party tweaking software such as Afterburner. You can get yourself quickly into an unstable setup doing so.

If you have an AMD GPU you need nothing more than Wattman in the drivers. For your CPU you should use nothing more than Ryzen Master.

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

This is not a question, as referenced in the guidelines Read This First . The post makes it pretty clear what it is, a central topic to centralise discussion about this particular issue. If you read the post and the external links, you'd see that it's confirmed to be a CPU issue, not a graphics card issue (I even included a "Cause" section if you read the post), and by extension it seems that all CPUs reported to be affected by this specific issue are AMD CPUs. I've already solved my problem. This is to help other people who may have been racking their brains for months like I was with the same problem.

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

-sum1-, I do not in any way believe this is an AMD issue.  It is simple misuse of poor quality utilities.  As pokester said and I have told many users, all that is needed is Ryzen Master.  Enjoy, John.

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

Well this is for questions for people needing help from other users. You are breaking forum rules then by not posting in general discussion. Your discussion doesn't belong here at all then.I was only trying to get enough information to try to help you.  Nobody can possibly see anything as you didn't give information just a bunch of general comments. I can see that you are pretty rude to people trying to help you. Glad you fixed your issue. Since you still have not really explained your issue with comments spread across literally generations of hardware or what fixed it, I am not sure how your intent is to inform or help the community. Have no fear i am quite sure I nor anyone else will attempt to help you again.  I am sure one of the AMD mods will be happy to put your post where it belongs. amdmattray_m

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

Why you would recommend a overclocking tool to pinpoint a systemwide shutdown, is over my head. And why you would consider it less junkwarish, than all the other "junkwares" coming from the manufacturers of specific hardware, even more.

Delving through two threads, it is quite obvious, that AMD does not want you to monitor their hardware...and that is the source of the problem.

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

pokester‌ I don't find anything rude about his replies and I don't know how he can be more clear about what he was attempting to do. Clearly, he is the one trying to help. I have been searching and searching while testing and testing finding no straight answers over the internet. What I did find was A LOT of people are having this problem with slightly different specs (different mb types, different RAM types, different generation AMD processors) but all are AMD, with no central place out there to DISCUSS the issue. So yes, I get what sum1 was trying to do here.  

Anyway, here is my situation. I changed my i7-7700 cpu on a ASUS prime b250-c motherboard with 16gb hyper X 2400m RAM to AMD 2700x on a ASUS prime x470 pro motherboard. At first i just used the hyper x RAM for couple weeks until I had money to purchase an AMD optimized 3200m RAM having no problems (even used AI suite to OC to 4150 mhz on cpu and still having the monitoring software used on my old intel cpu and board). In the meantime, I went to pc-parts picker and plugged in my build parts to find compatible RAM. I found the Corsair Vengeance LPX  3200M specifically saying AMD optimized right here on the box as opposed to the other suggested compatible RAM not even saying AMD optimized. So for obvious reasons , I went with that.  It was only after I installed this RAM that I began experiencing this exact random blackscreen issue described here.  I firmly believe the RAM change is just a coincidence and surely could not be the issue, but I just reinstalled the old hyper X 2400m RAM today and my system already feels more stable. Is this all in my head? It just doesn't make sense.

Re: Central topic for AMD random black screen/no signal issue, with power and reset buttons not working

I think the Memory Controller on Ryzen 2000 series and below are "sub optimal"
See: Asus ROG Crosshair Hero VII, Ryzen 2700x, Corsair Vengeance RGB (Pro) 3200 4x16GB Memtest86 failures... 

That link may be of help.

You should have saved yourself a massive headache and just gone for a Ryzen 3000 series processor.

Another thing to improve stability is remove the AMD GPU and drivers and install an Nvidia GPU.
