Hi so I just bought a Sapphire R9 290 Tri-X and I can't get it to boot to Windows properly when running two 1400p DVI monitors.

Previously, these monitors had been working just fine on a GTX 580.

Rest of setup:

i5 2500k (OC)
ASUS P8Z68-VPro
8gb RAM
Corsair HZ750 PSU
2 x Yamakasi Catleap 27" 1440p monitors

When I have both DVI ports plugged in:
- both screens show the bios post screens
- both show the black windows screen with the coloured animation
- then the screens go dark, they flicker after about 5 seconds, then go dark again
- windows does not boot (no windows desktop boot sound)
- screens stay dark, no HDD activity

***But*** it has worked twice out of about 30 attempts...so the DVI port is capable of putting out that resolution. If I reboot then it stuffs up again. Even swapping which screen was '1' and '2' for the Windows desktop made the screens go dark and hang the second time....

When I have one monitor DVI in port 1 and nothing else:
- usually works fine

When I have one monitor in DVI port 2 and nothing else:
- sometimes works

When I have one monitor in DVI port 1 and the other monitor connected by HDMI @ 1080:
- works fine

SO, my question is whether it is sounding like a software or a hardware issue???

What should I do, is a re-format required or would that be pointless?? I have reseated the GPU and reinstalled the drivers.

Thanks
*frustrated*

Additional info:
The AMD driver autodetect app says it can't detect the device, it shows the hardware as 0x1002 0x67B1 PCIE and doesn't recommend a driver...
It will boot as duplicate low res displays in safe mode.

I've put my old card back in but i've now installed every Windows update and done the updates for my mobo's bios (though it's over a year since last revision, i didn't have the latest), chipset, etc.

I'll give them a go with the new card and pray!

edit

OK so I've put it back in, here's what happens:

If both monitors are on – hangs on startup.

If both monitors are off:

- hangs from cold boot

- hangs from normal windows restart

- always works if I use the "RESET" button on the tower and wait until I hear the desktop noise to happen then turn them on...

WTF!!!!

Also, changing which monitor is "1" or "2" for the desktop also causes it to hang.

Does this shed any light on what's going on – is there a problem with the card/my mobo/my monitors??

Should I RMA??
