Can't get new motheboard to post with previously working r9 290

[roozor]

Just upgraded my ancient gigabyte Z68 ds3 to an MSI Z97. Changed cpu from a 2500k to an 4670k.

I can't get the system to post at all with my r9 290 installed. Soon as I take it out and reset cmos I can use the on board HD4000 and get into windows fine and reboot everytime with no problems. With the 290 in I just get a black screen, no hdd noise, no peripheral lights.

The very first time I switched the system on after building I got into the bios with the 290, made some boot changes, rebooted to install windows and it hasn't worked since.

Tried resetting cmos many times. Not sure why a previously working card refuses to work on this new motherboard!

Forgot to add it's the same case, psu, hard drives etc. Just a cpu,mobo and ram swap.

Check to see if your running the latest BIOS.

Updated to latest bios, still nothing. When I plug in the 290 it powers but no hdd activity, no mouse and keyboard lights.

I took the 290 out again to go back to working intel graphics but I just got some multi coloured lines. Rebooted and now I keep getting an infinite black screen.

Dead mobo?

This is turning out to be an awesome upgrade!

What PSU are you using? This points out to the card not having enough power or power cables not plugged in.

Probably your PSU went pop if no HDD activity.
Are you sure you used both the 24 pin and 8pin on the mobo aswell as the 6 and 8pin on the GPU ?

Tried a latest bios. Flashed it fine, got back into windows so I thought i'd try the 290 again. Still same problem. 24 and 8 in with 6 and 8 on 290.

PSU is only a month old, Seasonic M12 II Bronze Evo Edition 850w and it was previously powering my gigabyte motherboard, 2500k @ 4.7, 12GB hyper x blue and this r9 290

Booted up this morning for last round of tests before I RMA. I can't even get it to post without the 290 installed now. I used the on board graphics and as the 28 logo came up I got some fuzzy coloured lines and it rebooted. Haven't been able to get anything out of it since.

Right here's an update.

I managed to reset cmos with the battery out. Jumpers weren't working for that.

The system is all up and running with onboard graphics and 2 hard drives. I'm in windows 8.1 and everything seems fine for the last few hours.

When I add the 290 i Just get the black screen and no booting.

I'm sure haswell uses less power than my previous sandy i5 at 4.7ghz right? This is a stock 4670k. So I can't understand that my PSU might of gone or it doesn't have enough juice, yet it's still powering the system now.

SOLVED

As I was about the rip it out and send back to OCUK.... I noticed my 290, even though clicked into the motherboard could still be pushed down a few mm. I pressed down on the card while booting and it works!

Now in the process of modding my case I guess..

Antec 300 case - MSI Z97 G43 - Sapphire 290 reference.
