When I have my PC connected to my TV via the AVR (Integra DTR 40.7) and skipping forward in the video playing fullscreen it causes the PC to crash & fully shutdown, no BSOD, nothing in the event logs, just full system shutdown, have to toggle PSU switch sometimes to get it to turn back on.

Integra DTR 40.7 is on the latest firmware

LG 4K TV is on latest firmware

Running latest Nvidia Drivers (might try some older drivers soon).

Using MPC-HC - latest version (both stable and dev versions cause the issues)

Any ideas what would be causing this?

I can get it to happen 100% of the time with a particular video.

The PC doesn't crash when connected to two other monitors I've tested via HDMI, nor when connected directly to the tv.

Full system specs in my signature.

Thanks

What are the details of the "full PC shutdown"? Does it just turn off completely with no attempt to actually shut down the software? That is characteristic of quite a number of hardware problems, but the most usual one is a spot overheat of the CPU, which triggers its emergency power off to save itself from becoming damaged. This sort of problem is often able to be triggered by exactly the sort of thing you are seeing, where you run some particular software that runs some code that uses powerful CPU instructions. Those instructions work in a particular part of the silicon die of the CPU that is not normally used, and it just happens that there is (for example) not enough thermal paste above that part of the CPU, so it overheats. You tend to get this problem with old PCs where the thermal paste is degraded, but also in brand new ones where the paste did not spread out properly and cover the entire CPU die evenly.

Does MPC-HC have options to offload video decoding onto the GPU? If so, try turning them on and see if that helps. That should move the operations needing the powerful CPU instructions onto the GPU and avoid the problem. But if that works, it does point towards a hardware problem with the CPU that needs fixing.

Yeah PC just loses all power and goes from fully running to not powered on at all.

No trying to shutdown.

MP-HC is already running on GPU acceleration.

Let me do some CPU testing today.

Highest CPU core temp when it shutoff was 54 degrees, so not sure it's CPU temp.

Wondering if there is an issue with the video that's causing a fault in the drivers or similar that isn't handled so everything just dies?

After much testing, cable changing, different inputs on AVR on the TV, on the graphics card.....

Looks like it was an issue with madvr addon.

As soon I change the Directshow output to not use madvr, and blocked madvr as an external filter, I can't reproduce the system shut off.

So after much testing..

I got a new bequiet dark power 13 1000w and my computer is no longer shutting down...

However my 3D mark timespy score has dropped from 18,500 to around 11,500 in the latest Windows 11 insider builds!
Very significant drop in performance.

Windows 10 (clean install) - https://www.3dmark.com/spy/40148548

Windows 11 (22631.2048) - https://www.3dmark.com/spy/40148828

So now I need to work out if there are some performance bugs, or something in my install causing the issues.

I have XMP enabled, Rebar is enabled, latest BIOS and Nvidia drivers, and latest AMD chipset drivers all being used.

And just to hopefully close this out performance is back to normal in Windows 11
