[SOLVED] Rx580 8gb black screen with new motherboard

[haden2342]

Hello everyone,

Recently my motherboard was acting up (MSI 760GM-P23FX) and I decided to replace it with a Gigabyte 78LMT-USB3 R2. After installing this new motherboard with all the same components that were on the previous board (Windows 10, AMD Fx8300, XFX Rx580 8gb, and 16gb DDR3 ram), all I would get was a black screen after post. I could hear sounds from windows through my speakers so I knew that something was up with the graphics.

I took the card out and plugged the display into the motherboard and everything was working fine, no black screen. I have no clue what is happening, I've read that this graphics card works with this new motherboard. I thought it might be drivers, but I can't do anything with drivers without the graphics card plugged in since you have to download them through AMD's software and its auto-detection. I have tried to start the computer with the graphics card in and the display plugged into the motherboard but this just results in a black screen as well. Any input as to what might be going on here and how I can fix it would be greatly appreciated, thank you.

Is it possible to try another port on the graphics card? The Display Port, HDMI, or the DVI?
Not a likely solution, but better weed out the easy ones.

When I get home from work, I can try an HDMI port with a TV. My monitor is vga and I use a vga to display port adapter. With my monitor hooked up to the display port, I could see the post screens, bios, and what not, but it would go black after that so I don't know if the port or adapter could be still be bad and display that. Also this exact setup had worked just the prior day with my old motherboard.

It worked with HDMI and then I plugged my monitor in the display and now that magically works Thanks for the suggestion, saved me a lot of hassle.
