Hello, I'm an ADHD nightmare building a PC on my own for the first time (previously always had help from a more experienced person). I thought I had chosen all compatible parts and knew enough to get this done alone, but I was apparently mistaken lol.

The PC health check said that to install Windows 11, I needed to enable UEFI boot instead of CSM, but when I do that, the computer won't boot to Windows 10 anymore... just the BIOS.

I previously was able to run WoW (briefly), and then something screwed it up to where the battle.net launcher doesn't function.

I've installed all available windows updates (also previously tried deleting newer updates to fix the battle.net thing). It SEEMS like other issues I'm having are likely because I'm not updated to Windows 11 yet (I bought a key, but I can't get the software to install yet). All connections are seated properly and firmly.

I'm flailing at this point T.T Any guidance or immediate red flags that jump out? Is it the different DDR rates? Please let me know if I'm missing any helpful info. Thanks in advance for any time and consideration <3

PARTS LIST
Motherboard: MSI PRO B650S with onboard WiFi (i can't get the wifi to work because it won't let me install the drivers, even from an external source)
Processor: Ryzen 5 7600 (6-core, 3.8ghz)
Cooling: Cooler Master Hyper 212
GPU: Radeon RX 7600 (8GB, DDR6)
Power: Corsair RM850e
RAM: Kingston Fury 16GB DDR5
SSD: Crucial P3 2TB
 
With a new configuration, you really should perform a full, clean installation of Windows.

Should I relocate everything to plug into ethernet for this? I've been doing everything externally, including a usb wifi adapter because I don't have a cable long enough to plug directly into the modem, and the location of the connection is in the worst place possible.
 
Regarding the wifi drivers, you need to determine whether you have the AMD or Realtek components on your motherboard. Have you tried both?

I know for sure I have Realtek on this PC, because it shows up in the installed apps... but I don't think I tried to install the MSI Realtek drivers. I remember there BEING drivers. But I thought realtek was just sound. I had tried the Wifi and BT drivers. Can it have both? Could I still have AMD components?

This is what I found in the specs about the internet connections:

LANRealtek® 8125BG 2.5G LAN
Wireless LANAMD Wi-Fi 6E
The Wireless module is pre-installed in the M.2 (Key-E) slot
Supports MU-MIMO TX/RX
Supports 20MHz, 40MHz, 80MHz,160MHz bandwidth in 2.4GHz/ 5GHz or 6GHz* bands
Supports 802.11 a/ b/ g/ n/ ac/ ax
 
Yes and yes. The wired and wireless/BT can be different.

What you posted suggests you have a Realtek wired adapter and AMD wireless/BT adapter.
okay... thank you for clearing that up! i'm gonna disassemble and drag the pc over to the ethernet and see if i can get a clean install going on a hardline connection. i'll almost certainly be back because i'm a human catastrophe. 😆 but if not, thank you all so much for your smarts and assistance!

Good luck. Let us know how this plays out.
lmao i'm baaaack... after a clean install of windows 10 while connected directly to ethernet instead of wifi, i've got one problem left apparently? when i try to upgrade to 11, it still tells me that i need to enable secure boot to upgrade.

i followed the instructions that windows update directed me to, which told me to switch "CSM" to "UEFI" in my msi bios menu. But once i've done that, the computer will only boot back to that same bios menu... not to windows. so i don't know how to get past that, and i'm not sure how to explain this part to google to get any useful info back :sob::tearsofjoy:
 
Why a clean install to 10 and then upgrade to 11? You can install 11 directly, using the Win 10 product key.
oh... i assumed that if it wouldn't let me upgrade to 11, there was no way to directly install it without secure boot already enabled. so i started with 10. it previously wouldn't install 11 from my external drive either, though, so i don't know what else to do
