Hi,

My system

Ryzen 7 5800x
32gb ddr4 3600 mhz ram
Gigabyte Aorus B550M Pro P Motherboard (microATX)
Zotac 3070 Graphics Card
BlackMagic Decklink Duo 2 SDI Capture Card
Windows 11 (without the update mentioned to uninstall)

What happened?

I was doing a show where my PC was connected to a video wall, I connected two SDI lines to my BlackMagic card and had outputs to the wall using External Outputs.

I first noticed something was wrong when I ingested 3 NDI feeds that were choppy and we were on a gig network, but after I set up the external outputs, at random times my vMix would just restart itself, and come right back to where it started.

I eventually set it up to start external outputs on launch. But the damage was done, it had been a visible blink in the background.

There were also power surges and such before the show started that could have affected my graphics card or other components.

Also, the only other correlation to vMix restarting itself was an error I saw in Events Viewer that was nvlddmkm, \Device\Video3.

So far as of right now, I took out my capture card and swapped it for an Elgato HD60 Pro 4k, vMix hasn't crashed and restarted once.

I'm probably going to do a full reinstallation of windows anyway, but I wanted to ask the form where else I should look.

Try to stop the NDI feeds and see if this stop vMix from quitting. We have been consistently able to provoke vMix crashes with NDI sources being disconnected.

With the Gigabyte Aorus B550M Pro, DeckLink Duo 2 and NDI feeds are connected to the B550 chipset instead of the CPU PCIe lanes.

Not recommended by vMix.

If your PC case allows it, switch to an ATX motherboard like the Asus ProArt X570 Creator.

PCIe 1 = GPU (x8)
PCIe 2 = DeckLink Duo 2 (x4)
M2_1 = Windows SSD (x4)
M2_2 = RJ45 PCIe card 10 gbps via riser M.2 to pcie x4 (x4)

For optimal configuration:
Connect a PCIe 3.0 x4 card with an RJ45 10 Gbps port via an M2 riser to the M2_2 slot for NDI feeds.

Alternatively, use the motherboard chipset's RJ45 10 Gbps LAN port for NDI feeds and connect an M.2 SSD for recording to the slot. m2_2

Then
Clean reinstallation of Windows
Driver updates
vMix settings configuration
