Description

Hello, I've been using Rebar for almost a year now, I would like some help.
After resetting the BIOS settings to default, my video card stopped being detected. I get video in the BIOS and on the Windows loading screen. After that, the signal is lost and the video card fan stops spinning. Without the driver installed, I get video with the basic Microsoft driver, but as soon as I install the AMD driver, the video is instantly lost.

What I've already done:

• I tested another video card I have, also from AMD (RX 550), and it is showing video normally.

• I tested the card that stopped showing video signal (RX 5500XT) on another computer, and it worked perfectly.

• I tried to flash the x99 ROM backup generated with the dump, it didn't work.

• Reset CMOS.

• Disable Rebar with ReBarState.

• Recover Windows, with the option to keep the files and reinstall Windows.

Any suggestions, please?

Install basic driver, install rustdesk or similar and log on remotely to see what is happening: fans stop if zero rpm is enabled in driver.
Had a similar issue once - had to reflash modded rom...
