Black screen with new GPU

I just purchased a K450e and upgraded it with an SSD, 650 watt PSU, and Radeon R9 290.  Unfortunately, after installing the GPU, I get only a black screen.  I've been through previous posts and disabled secure boot and switched boot mode to legacy.  Still nothing.  The onboard graphics work if I take the card out, but when I put it in, I get no output from either.  Any help??

Re: Black screen with new GPU

Hi praziquantal,


Have you tried toggling the BIOS switch on the r9 290.


See the Details below from,15.html




The AMD Radeon R9 290 and 290X comes flashed with two separate BIOSed for testing. The bios can be toggled by the small black switch located on the top of the part closest to the mounting bracket that you plug your displays into. You must reboot after toggling the switch for changes to take effect.

Hope this helps

Re: Black screen with new GPU

I am having this exact same problem with a GeForce GT 610 on my new K450e. Have you been able to find a solution yet?
