Question RX 5700XT ROG STRIX BLACK SCREEN AFTER BIOS FLASH

[Banetrox]

I have this card from 2020, bought it brand new. Recently, I repaste the card and for my first time i replaced the thermal pads. First boot after cleaning and the fans of the card goes 100%. I reboot and then stopped. While I am gaming it makes a strange noise, I searched up and I found out it’s called coil whine.

So my friend told me to try changing bios to quiet mode. I didn’t know that my card had this option in the pcb and I flash my card while I was in OC bios. I downloaded the old flash tool with the win version because I didn’t know the process of the cmd version. Then I found the original (efficient) bios version of this card from the tech power up which was uploaded in asus support from the card but now it’s off.I restart my pc with my fingers crossed and it worked ! The next day, I boot and nothing..
Black screen. I can’t even see the bios.

Things that I have tried:
-Short the pins from the bios chip 1 and 8 (and 4-5)
-Tried to a different system
-I switched between the 2 bios of the card many times


The only thing that I didn’t try is to take a DisplayPort cable to try another output cause I use HDMI only.
My psu is 650w coolermaster mwe gold
It’s game over or still have a chance?
Sorry for my English

try the displayport cable and see if you get and display.
does your keyboard lights come on when you turn pc on?, like the numlock, or if you press "capslock" if so then its the display that is the issue., and you booted into windows. so changing the cables might works. just reboot and be patient it might take 1 or 2 tries. if not "power off,. ,flick the "bios switch on your card. " (most rx5700xt have this its by the 8pin connectors). then power on and see if that works if so then the other bios is faulty and needs re flashing..

As I said I already change the bios from the card and still nothing.
When I boot it seems that windows loading normally. My peripherals work without any problems.

 

[steveb1976]

does your computer have onboard graphics? if so try and boot into windows that way and if you can then check if the 5700xt is showing in the "properties section.. it could be the card got corrupted with a bad bios flash.. if its showing and your in "onboard graphics." you can try and "re-flash the card" via the flashing app.. if you still have the "new bios" of get it again from techpowerup.

How to boot from the onboard graphics while the pcie express is used?
I tried the hdmi cable to the motherboard while the gpu was running but again black screen.
Also I took out the cmos battery to reset mobo bios..
I have integrated graphics.

 

[steveb1976]

if the onboard/integrated graphics port did not work either. .then i would suggest you get a local computer store to take a look as it could be you damaged the bios on the gpu or the bios on the motherboard when you tried to short it

 

[Banetrox]

I tried with onboard gpu again and it worked but still windows can’t find the card..
in amdvbflash says no adapter found.
I tried the dos version also and all the version that supports 5700xt
Again nothing..

your card have 2nd bios turn it

 

[Banetrox]

As I said before I already done that..

 

[steveb1976]

then worse case senario is you bricked your gpu,, there are videos on youtube on how to unbrick them, but its to extensive to go into on here. so you might want to search youtube for your specific card make and model and see if you can do it.. ive had success doing 5700xt's ,5700 ,5600xt ,580 from saphire ,xfx,msi.. but you will need patience. if not sell it on ebay as parts and get a new card

 

[Banetrox]

so you say that is game over right?
any other fixes?

 

[steveb1976]

you would need an expert to physically check it out.. it maybe bricked from the bios flash.. it may just need to have both bios's re-flashed... or ir might be that the card was faulty .. its hard to say without seeing it in person... a local store might be able to help , unless you can return it to where you got it..

like i said... ive bought many cards like your from ebay when people sell them as faulty. and i fixed most with bios flashing. (you would need integrated graphics on a motherboard with 2 pcie slots. ) where did you get the card. as a majory of people used to use 5700xt's as mining cards. and why they need bios flashing back to stock. for 1 or both bios's on the graphics card..

also have you tried another card in your pcie slot.. to see if the slot was the issue
