Windows boot freezes when dual monitor are connected (NVIDIA card)

[Baddass]

I'm facing a weird issue and can't think of anything else to try, so I'm wondering if anyone has any suggestions. Whenever I boot my PC (from shutdown, a restart or even loading from hibernate), if i have two monitors connected, the system freezes just before it would normally progress to the logon screen. The only option then is a hard reset/shut down.

Everything works fine with just 1 monitor connected, and i can connect a second and use it fine once it's loaded into Windows. I've just been unplugging the second monitor each time i shut down for now to avoid this issue when it next starts up, but that's obviously annoying.

System info is below and I've already tried a complete driver clean in safe mode using DDU and a re-install fresh when back in Windows normal mode.

• Windows 11
• NVIDIA RTX 3090, latest drivers
• Both displays connected via DisplayPort outputs from the graphics card (does the same if i use HDMI)

I'd look to replicate the issue from a linux live usb first maybe? Not sure if you can sleep/resume from a linux live, but maybe try booting into say linux mint with both monitors plugged in, might be the first easiest step to determine if its hardware (like some weird PSU protection kicking in or something)

thanks for the suggestion. I guess i could also try booting up with an AMD card and see if that does the same...would identify if it's the NVIDIA card specifically, or something else like the PSU or motherboard?
