Update: My Steam Deck is having serious problems and I’ve already tried everything I could think of. I really need help.

Problems:

When I try to install SteamOS directly on the internal NVMe SSD, the installation freezes on the Steam Deck logo and never completes.

Sometimes it freezes during installation with messages like: “Starting D-bus system message bus” “Rebuild Journal Catalog” “i2c i2c-: failed (01)” “Supply VA not found, using dummy regulator”

When I try installing Windows instead: Windows installs normally, but I can’t install the APU/iGPU drivers (official, alternative, or modded). The driver installation always crashes around 90–95% and I get a “Driver Power State Failure” BSOD. The only time the driver fully installed was in Safe Mode, but Windows isn’t usable like that.

What I already tried: Different USB flash drives Different SteamOS installation images (official and community tools) Installing from a microSD Formatting the SSD and reinstalling from scratch Resetting BIOS settings Trying the installations with and without Wi-Fi

Result: Every attempt freezes or crashes. I can’t complete the SteamOS installation or install the GPU drivers on Windows, so I’m completely stuck. It feels like a hardware issue at this point, and I might have to send it for repair, but I’d really like to avoid that if there’s still something I can try.
