[SOLVED] Weird colours on boot-up screen ?

[MaazBinAli]

Experiencing strange boot-up screen colours after making a few changes and installing Windows 11 from Insider Programme (Beta Version)
In order to install Windows 11, I made the following changes to my PC:

• Converted boot drive from MBR to GPT
• Enabled PTT (TPM 2.0)
• Enabled Secure boot in BIOS

After these 3 stages (in photos) Windows boots up and displays the lock screen and then desktop normally.
Anyone who is experiencing a similar issue, or has any idea why this is occurring?.

Sorry, I'm new to this forum hence I was unable to figure out where to upload the photos from. My GPU is an RX 580 2048sp and Motherboard Gigabyte H310m s2h.

gpu bios update is needed if you want to resolve it

download gop update from second post, then follow instructions from first post

before you start, make sure you backup your current GPU bios, if GPU gets bricked, you can recover it with another GPU plugged in PC (integrated GPU counts aswell)
GPU-Z can do gpu bios backup, guide here

So essentially I'm supposed to flash my GPU BIOS to stock?.

if manufacturer offers gpu firmware update, then yes, you can use that one
