Trouble Booting Windows 11 on ASUS B450M-A: ACPI BIOS Error

Asked By CuriousPineapple42 On

Hey everyone! I'm experiencing some serious issues with my PC. It started crashing apps and then suddenly, it won't boot into Windows 11 anymore. Here's what I'm working with:

- **PC:** MouseComputer SL6-G (2020)
- **Motherboard:** ASUS B450M-A
- **CPU:** Ryzen 5 3500
- **GPU:** GTX1650
- **RAM:** 8GB x1 (2666MHz)
- **Storage:** M.2 SATA SSD

Now for the weird stuff:
- My PC has random blackouts.
- Windows gets stuck at "Automatic Repair" and then shows an ACPI BIOS ERROR blue screen.
- Using any Windows installation media also leads to the same error, even if I take the SSD out.
- However, I can boot from Ubuntu installation media by adding "acpi=off" (the SSD is removed, and luckily, I recovered my data).

Here's what I've already tried:
- Replacing the CMOS battery.
- Resetting and updating the BIOS.
- Turning off PSS Support.
- Checking UEFI/CSM settings.
- Trying a single RAM stick in different slots.

Since Ubuntu works without ACPI, I'm starting to think it might be a problem with the ACPI table on the motherboard, or could it be a failure of the CPU or another component? I'd appreciate any advice on what steps to take next!

It sounds like you might need to check your dump files for a clearer idea of what’s causing the BSODs. If you can boot into Windows (or Safe Mode), look in C:WindowsMinidump for any crash logs. Zip those files up and upload them to a file-sharing site—something like catbox.moe usually works well. Multiple dump files would help a lot, so see if you can tweak your settings to get Small Memory Dumps if needed. This can give us more insight into what's malfunctioning!
