Hello,

Sorry for the lengthy post but I am in desperate need of help with my new graphics card. I have already RMA one R9 390 back to newegg and I got a replacement in the mail today with the same exact problem as before. I am now worried that it is on my end rather than a defect with the card but I suppose it is possible to get two defects in a row.

After I installed the card (both the original and replacement card) all I get is a black screen on my monitor. No POST screen, no beeps and my back-lit Logitech G510 keyboard remains dark (it normally lights when the PC switches on). When I swap back to my old Radeon 6970 graphics card everything works.

The 6970 has two 8pin power connectors and this new card has one 8 pin and one six pin. I have a modular Corsair AX1200 PSU and I used the same two 6+2 pin connectors on the R9. One 6+2 connector is plugged into the 8 pin port and the other 6+2 connector is plugged into the 6 pin port with the +2 hanging off to the side. The MSI logo lights up on the card and the fans spin up as they should, beyond that I cannot tell what is happening without the display.

I attempted the following steps to troubleshoot from MSI support. They were not the greatest help as they suggested things I already said I attempted in my support ticket so I got a little frustrated and found my way here.

1) The connections were checked several times since I swapped out the MSI card with my old video card a few times and each time I ensured the power connectors were secure

2) I have a Gigabyte G1 Assassin2 motherboard, and flashed the BIOS to version F11 (latest non-beta version) since it was a little out of date on my first attempt. It made no difference. I verified the board compatibility with the card on some online parts directories and they appear to be compatible with each other. Unless someone can tell me differently. https://pcpartpicker.com/parts/video-card/?compatible_with=gigabyte-motherboard-g1assassin2#m=27&c=311

3) I have a Corsair AX1200 PSU with modular 6+2 connectors which runs my previous two 8pin video card with no problems. So I do not think the problem lies there. I even tried plugging the 4+2 cables into different unused slots on the PSU and there was no difference.

4) I have verified the PCI-E slot with my previous card and the PCI slot is working. I also used another PCI slot on my board and there was no change.

5) MSI suggested I test the card on another PC but I was not able to do that since I only have one PC.

6) After getting my replacement card from newegg I did one extra step today and replaced the operating system SSD with my new 1T SSD hoping it was a driver issue but I still did not make it to the POST screen to start a fresh Windows install. I also tested the new SSD and it works fine when plugged into an open SATA port.

Here are my specs:
Windows 7 64 Professional
256GB Crucial M4 SSD with my new Samsung 850 1T on standby until I sort this mess out
4TB Seagate HDD x2
3TB Seagate HDD x1
2TB Seagate HDD x1
Gigabyte GA-G1.Assassin2 (BIOS F11)
Intel Core i7-3960X
16GB RAM
Corsair H100I GTX Liquid Cooler
Corsair AX1200 PSU
CM Stormtrooper Case

So now I am back to using my 6970 and my head is spinning. I am hopping that some wise soul can point me to so obvious solution that I missed. Is this card defective like the last one or am I missing a step? I do not remember things being this difficult during my initial build two and a half years ago but my memory fails me at times. Could there be a problem with the BIOS not recognizing the new card, do I need to clear the BIOS settings on the assassin2 somehow?? Any help would be greatly appreciated. I just want to be ready for Fallout 4 lol. Thank you.

I am using a DVI connection to my monitor. I will try to switch to HDMI to test. I will have to steal one from my Playstation setup first. I will let you know when I swap them out.

So I just swapped out my DVI cable to an HDMI and I still have a black screen on the boot. No post, no difference than before. I switched back to my old card and everything is fine again. I did notice that as soon as I plugged in the HDMI, the monitor seemed to recognize that it was plugged into something because the "searching for signal" box disappeared. But as soon as I powered on the computer the screen went to black and fell asleep as if it was plugged in but had no signal. This happened when plugged into the DVI port as well.

Can this be a compatibility issue? I thought the only major concern is the power supply (I have 1200W) and as far as I can tell my mobo can handle the card based on the online specs. Unless I missed something.

Should I just contact tech support and send this one back too for a replacement? I don't want to waste their time but then again all indicators seem to point to a bad card again at this point. Any other advice out there? Thanks.

Solution found, for my problem at least. I RMA'd the card and got a new one in the mail. Prior to installing the new card I noticed on a forum somewhere else to disable UEFI support and switch to legacy ROM in the BIOS. I did not believe that this would work since the R9 clearly states it is UEFI compliant but I did it anyways. When the new card came in I plugged it in and it worked!!!! (I later had to remove all drivers in safe mode but that was easy).

So one of two things happened:
1) I simply got two DOA cards and the third one worked
2) The UEFI option in the BIOS was the problem.

Either way I am not turning UEFI support back in because if that shuts down my card that means I will have to put my old card back in to boot up my PC just to get back in the BIOS to disable it again and I have stared at the guts of my machine too many times these past two weeks to do that again. So Redhavnen give it a try on disabling UEFI and switching to legacy ROM support with a working card installed then install the new R9, if that does not work you may have just a bad card. Time to play some more Fallout 4, I will be MIA for a good six months because of this game LOL. Good luck Redhavnen.

You have to go into the BIOS and look for anything that has that UEFI or ROM language in it. Also look for anything to do with the PCI slot or legacy support. Every board is different, so it may take some hunting.
