Scrambled screen

[RichardStones]

Hello everyone!

I've got a completely new build, where the GPU has already been changed twice in efforts to fix the problem. I am looking for some more context before talking to the warranty team.

Context: The PC screen was getting scrambled regularly after every shutdown. On next boot (after normal shutdown) the PC starts up with scrambled screen (pictures included). It was necessary to shutdown on physical power button, and then boot up PC normally. I've solved this issue by disabling "Fast Startup" from the power options. Shutting down the PC now works fine.
However, today I left the PC on for 5-10 mins while I got to grab something, it went to sleep mode, and when I got back and moved the mouse to continue using it, I got the same scrambled screen. 

My first question is, is it normal for a build not to work with "Fast Startup" on Win 11 Pro? Is it a software issue from MS side, or is it a HW issue? Should I be concerned, or just disable it and move on.
My second question is essentially a follow up, what to do with this sleep mode into scrambled screen issue? I can't help but think it's connected to the "Fast Startup" issue, but it is disabled. Do I need to change some settings on my PC?
And again, is this normal. Should I need to change any of these settings on a new build, because it's expected they don't work great atm due to software issue from Windows, or is it expected a new build should work just fine.

This is the build: https://cz.pcpartpicker.com/list/cGrsHG
I am using 34" Dell S3422DWG monitor.

Thanks in advance for all the help!

I disabled fast startup as soon as SSDs became a thing. The gain in boot time is negligible for the hassle that hybrid hibernation mode brings with it. Is it normal that it fails ? Certainly not, but I know lot of issues that can be resolved by a complete shutdown and power up, thing that fast boot bypasses.

Frankly, disable and move on. You don't need it and you won't miss it.

There is something that interferes with the sleep mode for sure. I'd test the RAM with Memtest86 and check the health of the boot SSD with Crystal disk info to be sure. You can also check your peripherals in device manager to see which ones have the "Allow Windows to shut down this device to save power" enabled. I suspect that one of these (maybe the GPU itself) should not have this option enabled in the first place.

If you can't find why the sleep messes with the screen, you'll probably want to deactivate the sleep mode. You can define a monitor off timeout that acts as a sleep setting for the monitor only. It should be safer than the computer sleep feature.

Again, this isn't normal but it is in the possible realm. If you don't locate the source of the issue, it may be an incompatible Windows update that hopefully will be fixed in a subsequent update.

A new build should be working as a new car. But even new cars suffer from issues and recalls

Good luck !

This super looks like a monitor or cable issue that I'd get in the shop with some regularity a few years ago.  One person had a super high end dell medical monitor that he had to power off by the plug and plug it back in to it's adapter before it'd come on. turns out it was a 10' cheap HDMI cable on a really high resolution monitor and doing the "full boot" like your Windows does would resolve it. Tried a cable swap for giggles?

 

If not, I'd try using a different connector input temporarily, like if your screen has 2 DP choose the 2nd one or use an HDMI on lower resolution instead if you can.  The output from the graphics card is less suspect but still a valid troubleshooting target. Worth a shot anyway

Hello, thanks for your response.
I did a full memtest86 run, took around 3 hours, and there are no errors with the memory and SSD.

Regarding the "allow this device to shutdown" I can't find that anywhere in the device manager tabs. Is there another way to check for this?

To summarize, to follow the new car analogy, it isn't any of the car parts, but the infotainment system version, which will likely get patched up in future version?

Hey, thanks for your response.
So, the thing is, 2 of my other much older PCs have 0 issues with the DP cable, and I've been using them extensively for quite some time. I also connect some work laptops via HDMI, and it works great. Nevertheless, I could try a new cable.
The monitor however, has only 1 port for DP.

I really hate cars that went infotainment containers these last years

I used to fix my stick shifter with some bolts and a few occasional welds. Now, you can't even ground a welder without frying the onboard computer...

Just a fun fact, I own a Ford Escape and the infotainment system needs to be upgraded to receive any updates. This upgrade would cost around four grands if it is available at all. That's why I drive with outdated maps, no onboard wifi and the sirius receiver no longer receives anything. Lol
