Help with MSI r9 390 8g gpu

[Nitro816]

I'm switching from an AMD Radeon 6900 series card to a MSI 390 and I'm having some issues. I uninstalled the drivers using DDU, removed the old card,and plugged in the new card. When I start my pc, my monitor says that it isn't receiving a signal from my computer. I've tried two different hdmi cables, and a dvi-d cable. I've had no luck so far. Before I bought the 390, I noticed that it required a 3.0 slot and that my old card used a 2.0 slot. I asked Reddit and was told that a 3.0 works in a 2.0 and that it'd be fine. That's all I can think of as far as what the problem might be. Any suggestions on how to solve this are appreciated.

PCI-E 3.0 capable cards work perfectly well in PCI-E 2.0 motherboard slots. I have an R9 280x (PCI-E 3.0) in an ASUS Sabertooth 990FX v1.0 mobo (PCI-E 2.0) so that is definitely NOT your issue.

Can you confirm you have both power connectors hooked up from your PSU to your GPU (either 8/8 or 8/6 pin).

If so, I would go back to basics. Re-install your old 6900 series card and confirm you can boot into windows, you should not need to install any drivers to do this as the default MS driver will work without issue. If this works fine, reboot into BIOS and check its version. Check on your mobo manufacturer website for later BIOS versions (you never know they may have had to release a BIOS update to support the 390 card??) and upgrade to the latest version.

If none of the BIOS elements apply and there are no other settings you feel are linked to your display/PCI-E slot the nre-install your 390 ensuring you've got the requisite power connectors hooked up (and its in the primary PCI-E x 16 slot)

Let us know how you get on. Good luck.

i believe your card needs power to it you should see some pins it should be the pci -e connector i believe. if you have a modular power supply make sure to use the pci-e power ports.

I plugged both the 8 pin and the 6 pin power cables into the card. That isn't the issue. The card lights up and runs. I put my old video card in and booted it up and everything was fine. I'm not sure how to find out what kind of motherboard I have. I'm looking at it and I don't see a brand name on it. It's the one that came stock with my Alienware aurora r3, and I've heard that Alienware doesn't have the greatest motherboards.

FYI I bought an MSI 390x and could not get the computer to post, black screen, fans running, lights on, but nothing else. Returned that for a Sapphire 390x with the legacy bios option, with the legacy bios activated, the computer turned on and worked first try. I also have an Aurora R3.

People fall victim to this problem everyday with the aurora r3, I own one and this has happened to me before when I bought an r9 270x and it did not get signal. Here is the full answer of why it will not work with some cards but will only known to work with cards that have a dual bios switch...

It should work if you have 875w PowerSupply, and it has the proper-pinned power-plugs natively.

Since it's Aurora-R3 you better get one with a Dual-BIOS switch that supports both Legacy and UEFI Hybrid.

Aurora R3 is maybe just EFI (not true uEFI) so it can't decide which it needs. Save yourself a lot of trouble and get one with a switch on the video-card.

Reportedly, some newer MSI & Sapphire cards have the switch.

You might have to un-snap plastic video-card air guide if it exhausts into case.

Edit: I have this from my notes that someone wrote:

Just wanted to say that the R9 380 does work. But you have to buy a hybrid BIOS graphic-card like "Sapphire R9 380 Nitro". The Sapphire cards are able to switch the BIOS boot from UEFI to legacy BIOS. There is a small "switch" at the corner of the card you can use. It works fine without any issues.
