[SOLVED] GPU Upgrade boot loop and unable to get to safe mode

[steventhegreat20]

OS: Windows 10 (an old version)
Cpu: Ryzen 5 2600
Motherboard: ga-ab350-gaming (rev. 1.x)
Old GPU: rx 550
New GPU: rx 580 OC 4gb
Storage: crucial mx500
PSU: corsair cx450 (450 watts)

Maybe it is important to mention the PSU is 450W and it has only one 6 pin connector (a 6+2 connector).

I removed my rx 550 and put in the rx 580 (without connecting the 6 pin connector) and booted up my PC and it was a black screen with a cursor and then it became a pixelated green/pink screen for the gigabyte logo screen then the windows recovery screen. I put the 6 pin connector into the rx 580 and nothing changed. I did not uninstall the rx 550's graphics drivers before doing this. I put the hdmi cable into the motherboard and the screen stayed black. I then put the rx 550 back and the hdmi cable into it, the screen started and it was the same. The gigabyte logo came and then the windows recovery screen.

The boot loop begins whenever I select any option in the recovery options (I haven't tried wiping my drive for the windows re install option). I want to get to there and uninstall my AMD drivers but I can't get to that point without it boot looping.

I have tried:

1. All the 9 options in the trouble shoot advanced options.
2. Enabling safe mode in CMD (I could not use shutdown /r or shutdown /r/t 0 or any of the commands because it won't recognise "shutdown") but I can't restart the pc without it going back to the boot loop.
3. Repair
4. Enabling recovery OS rather than windows 10
5. Windows 10 reset but keeping "Personal Files"
6. Disabling fast boot in the gigabyte BIOS
7. Removing the CMOS battery for 10 seconds
8. Re-inserting the ram (into the same slots)
9. the cables are the same, they are not loose or have been moved.
10. putting the 6+2 pin connector into the two different ports of the rx580

I have been shutting down my pc by turning off the power supply at the back.

I had updated to the new AMD Adrenalin graphics driver a week ago with the rx550.

The boot loop has now stopped since I tried to wipe windows but keep "Personal Files" and it is stuck on "scanning and repairing drive (C 100% Complete" for the last 30 minutes.

I can take pictures if they would help.

Thanks if you can help.

1. Download the win10 ISO, and make the USB bootable media. How to https://www.windowscentral.com/how-create-windows-10-usb-bootable-media-uefi-support
2. Remove the rx 580, put the rx550 back, like other member said, the PSU (corsair cx450 ) can't handle the rx580.
3. Then try the startup repair method to fix the problem. How to https://www.windowscentral.com/how-use-startup-repair-fix-boot-problems-windows-10

If you want to use the rx580, buy other PSU. Also use DDU to uninstall the GPU driver, before you install the rx580.

get a new good psu with 2 6+2 pin connector

apologies my psu does have an 8 pin, it is a 6+2 and i used a 8pin to 2x4pin splitter. it is 450 watts but i saw that this is exaggerated and an rx580 only takes 340-360 watts and the system wont get past 450 usually so i dont think it is the psu's fault. it has 2 6+2 pins.
