Powercolor PCS R9 290 upgrade problem No Display

[MikeRevelation]

Hi all I'm having trouble trying to upgrade from 2 Ati Radeon 7850s crossfired to 1 Powercolor mentioned in title. I bought this card from Newegg with this actually being the second unit because I returned the first unit for the same issue. I followed this particular site's tutorial on how to completely every piece of AMD software and drivers off the computer before putting in the new card and still no display. Here's the tutorial link:

For questions about compatibility, here are my specs:
AMD FX-6300 Six core Processor
Gigabyte Ga-990FXA-UD3 F2 motherboard
Raidmax 730w Power Supply
Windows 64 bit
8 GB ram

I have looked on every site I can and even ask AMD Tech support and they confirmed that motherboard and the graphics card were compatible. I even saw on some sites that people suggested update the Bios in the motherboard which I did, but with the same results.

Any suggestions at this point would be amazing. Thanks!

Don't do that.


You should try use the DDU to uninstall the driver in safe mode. http://www.guru3d.com/files-details/display-driver-uninstaller-download.html
2nd that is the question for the Raidmax 730w PSU, cf hd7850 will draw less power than the single r9 290. And we know that PSU is not the good one, if you have other PSU try it. More info for PSU http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
Maybe the r9 290 has problem, test it in other pc.

I just used DDU to uninstall all the drivers then shutdown the pc to install the new one. After installing the new card, I downloaded newest drivers and installed with no luck. Like I mentioned in first post, this is the second unit so I don't believe there is a problem with the card. I don't have another pc or PSU to use. I checked on PC Part Picker and included the graphics card, PSU, motherboard, and processors that I have in my pc now and it said there were no compatibility issues.

Then you need think about to buy the better PSU, or go to local pc shop to test the GPU, but I think the problem is the Raidmax 730w one, even it does label 730W, but it doesn't mean it can output that much, it is the one no 80+Certified.
