Just installed r9 390 into PC, crazy problems happening already

[SlickJava]

Alright, so lets start from the start.

I bought my new r9 390 to fit into my PC.

But the moment I installed it, and started up my PC stuff started to go down.

1. My PC would turn on for 5 seconds, then it would turn off. This was using the 8 pin adapter provided with the graphics card.

2.4. I put in my new graphics card again, but instead of using the 6 to 8 pin adapter I used the 6pin + a seperate 2pin to connect to the graphics card. PC started up fine, no problems but NO DISPLAY

3. I put in my old graphics card to see if I destroyed my PC, but everything was fine. There was an display, I logged in, nothing was corrupted.

4. Now I am stuck here thinking what the hell to do.

One thing that I think is causing the problem is my 600watt Silverstone power supply, and if that is the actual problem, then I would have to get a new PSU 🙁

Can anyone help me solve this problem?

(I'm running Linux fedora if anyone wants to suggest driver stuff)

Thanks,

It may be a PSU issue but try just 1 stick of RAM on it's own in slot one, if it still happens try another one its own. Do you happen to have a spare PSU to try?

what are your specs and stuff.... like the motherboard

Maybe it's just the way you've written it, but it sounds like you are saying you only used one 6 to 8 pin adapter. As the card require 2 power leads, what did you use for the other?

what is the model of the psu? all we know is a silverstone

Right,
Gigabyte GA-X79-YD3 Dual UEFI motherboard
Intel core i73820 3.6ghz 8 cores
16gb ram
gigabyte gtx 260 (yes very old graphics card)
600W strider plus silverstone v1.0 psu

It had a 8pin slot and a 6pin, connected them both

I tried what you said there with the ram, still the same problem - no signal to monitor but everything starts up fine.

go into the gigabyte bios and choose "Bios features" and "boot selection mode" if its only on UEFI switch it to UEFI and Legacy mode. But you must put your old GPU back in to get a display to see the bios... after you do that save and exit, take out the old GPU and put the new one back in

This was what I did after hours of troubleshooting! I change from EFI to legacy mode, and everything worked. After all the hassal and clean up, I return to this post I did - and the solution is right here! Well, thanks for it, and ill mark it as best solution so anybody else that gets this problem can solve it.
