I've got a bit of a strange issue, I've got a Asus B650e itx motherboard with 32gb g.skill DDR5 6000mhz CL30 ram and a 7900X3D CPU in it, it's a machine I build for my Mrs, it's connected to a 65" 4k Toshiba TV and does almost everything she wants from it, it's recently it's started playing up a little when playing games, and what I've discovered is for some reason, although I keep disabling it, it randomly keeps enabling the integrated graphics, I'm using a 7700XT GPU so don't need the onboard graphics, it works fine when iGPU is disabled, but I don't quite know why it keeps switching itself back on again in the bios, I only realize this happening when I launch a game and it's completely unplayable, it's more than laggy, I reboot, enter the bios and hey presto the only that has changed in the bios is the iGPU is enabled again, if I disable it and save and exit, the game is fine, until the next time it happens, any ideas anyone ?

It's running all the latest drivers and the latest official bios (non beta).
 
Are you using a riser? I wonder if the card has issues being detected properly and it resets for some reason.

Silly question I know, but you're definitely not connecting your TV to the motherboard display ports instead of the graphics?

Yes it is using a riser cable, sorry forgot to mention it's in a jonsbo A4 case sandwich ITX, changed the cable for a gen4 cable, so maybe it could be that.
But the hdmi cable is deffo plugged into the GPU not the motherboard output.

The easiest way to test it, is to set the PCI-E version to 3.0 in the BIOS. If it fixes the issue then likely you have a bad cable.

So a bit of an update, the PCI-e cable was running at x8, after removal, a bit of a clean up and refit its running at x16 again, but the PC was doing all kinds of strange things, during post it did a double post and came back on again stating that for some reason it had enabled CSM mode, so I decided to back flash the bios and ram test all night after setting up the bios, so far so good, but its still early.
