I understand. You are only able to boot to the desktop by using recovery mode to do so.
This definitely points to a Graphics issue. The drivers you have should be sufficient. You may need further boot parameters.
Can you please try the grub parameter radeon.dpm=0

[HOW TO] add a grub parameter

There may be times that a user must add a specialized grub parameter in order to overcome an issue. The purpose of this guide is not to provide parameters, as that would be a case by case basis. It is to provide a guide on how to add one. To add a parameter, in a terminal (TTY, Recovery Prompt or Terminal Emulator) run: sudo nano /etc/default/grub Arrow key down to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and place your parameter within the quotation tags. For example if you are adding th…

@deadin2

Which line should I be inserting this

Arrow key down to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and place your parameter within the quotation tags. For example if you are adding the nomodeset parameter, it would look like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

In your case, it would look like: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=0"

Alright done now reboot?

[Aravisian]

yup, reboot to test

[deadin2]

Alright rebooted normally without recovery still issue persist

[Aravisian]

Ok, please replace that parameter with amdgpu.dc=0

It would look like: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dc=0"

[deadin2]

No luck still the same

[Aravisian]

I am not sure of others we can try... may need to try some Internet searches. Currently, I need to go take care of other things and will be offline for a while.

[deadin2]

Sure man thanks for the help

[deadin2]

Hope this will help btw I can connect to the internet now using my phone and a usb connection

Question: Does it work if you boot into the LiveCD?

Also: If you have a Mobile phone that allows USB tethering, plug the phone into the computer via usb, enable tethering, reboot. and then try update / upgrade suggested by @Storm

Let's try:
radeon.modeset=0
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0"

Don't forget to run
sudo update-grub

Doesnt work

Try taking the card out, and putting it back in in case there's any oxidization in the contacts. And make sure all the wires are tight,

if that fails, are you comfortable with taking hardware apart? a radeon 5k is an older card and there is a good probability the thermal paste is shot, if you are up to it, take the card out, take it apart, clean the die with rubbing alcohol reapply a dap of new paste and reassemble and try again.

Maybe it's time to look at purchasing a newer video card. If the motherboard has integrated graphics, possibly leaving the video card out for now.
