Gpu fans stop spinning but card gets hot and the screen is black during driver install

I gave my fairly old pc to my gf last year and it's been running smoothly ever since. It's an i5 2500k not oc atm, water cooled and i replaced the paste a few months back, its gpu is an R9 390 sapphire 8gb oc edition from gigabyte, ram is in good shape and anything but the power supply who was bought around 2 years ago and is probably 80 plus from NAXN is in mint condition as i took care of this PC and upgraded it myself over the years until I decided to get myself a new one.
The problem started a few weeks ago but i only got to it about 5 days ago and i've been trying to figgure out what is wrong with it to no avail..

So what the problem is from what I've seen: I can boot into safe mode and stay there for as long as I want, watch youtube/twitch or browse anything with no problem. As soon as I try to boot into windows normally my gpu fans stop, my screen goes black but the card stays on and gets hotter and hotter. The one way i could get into windows normally was to uninstall my drivers with DDU in safe mode and then boot woth no drivers installed; the problem with that is either windows is going to try and install amd drivers automatically for me and then my pc does the same thing as when i tried to start windows before, or I try to install drivers manually (have tried old and new alike) and during that install the screen goes black and the fans stop but the gpu keeps getting hot just like before.

I have tried swapping power cables that go into the gpu (2x8 pins) with new ones but that didn't work, i have also tried resetting my bios through the bios itself but also by taking out its battery and placing it back in. I have bought a brand new sshd to reinstall windows which I did 3 times at this point.

One other thing i dont get is why my bios screen has a black background filled with SHORT horizontal pink lines (not long all across the entire screen) and something that resembles a bunch of blue letters covering the lower half left of my screen in blue.

I believe I have tried everything and nothing i read up online was able to solve my problem for i have not seen anyone with my issue previously.. I am out of ideas. Is the card dieing? Is the PSU dieing? Is the MB dieing? what can I do?

Writing here was my last resort, i really do not know what else I could do, if you guys could help me out I would really appreciate it <3

UPDATE: I went ahead and bought a new power supply, 750W RM750 from corsair to make sure my psu was not the fault and after i installed nothing was different even after attempting to install new drivers and even tearing my pc appart and rebuilding it open on a cardboard box so that I could use the other PCI slot on my motherboard to see if maybe that was the fault. Right now I have no other idea of what to do, I've narrowed it down to either MB or GPU.. what do you guys think?

Hmm, i was not aware. In any case my motherboard does not support it so i cannot use onboard graphics anyway.

this is the best way to check monitor cable and monitor also that will tel you if video work so you could test gpu in another system and see if the fans on it work you could also use gpu-z rendering option and check your temp and fans speed with hwinfo sensor page .

Your GPU might have been traumatized by heat, I would
- Improve airflow around graphic card: Slap in couple 120mm adjustable speed fans by the drive cage blowing air horizontally above and below graphic keeping computer tower side panels open,
- Boot using the integrated graphics (intel HD 3000) through motherboard display output then access the Bios and insure primary Display Device is set to PCI ( or PEG )= your R9 390 graphics save/exit/reboot
- Switch display connector to your GPU R9390, check whether AMD control panel is available when right click on desktop contextual menu or in the systray if not reinstall up to date AMD crimson software after sanitizing graphic drivers with DDU-in safe mode.
- Monitor closely :Run Hwmonitor to check GPU temps clocks and usage and fan speed (keep an eye on GPU fan)
- Customize fan curve and cooling: run MSI afterburner to adjust GPU fan to keep card below 40 while idle and adapt it to loads and gaming to maintain card temp below 75 while helping it's cooling ramping up RPM of previously added fans.
- To complete your Intel HD graphic driver installation, switch primary display in bios to IGPU or GFX, save/exit/reboot switching display connector to your motherboard display output ( amd control panel shouldn't be available on your desktop) and proceed installing Intel graphics drivers and control panel.

The card was dead, got it replaced and now pc works.
