The XFX R9 Fury will not show a signal. Most of the time it will power on, the pink light will turn on for a split second then go off, the fans go to full speed and no signal shows on the monitor. Every now and then the light will stay on for about half a second and the monitor will show a split second of the first Dell boot up screen before the light and screen go off and the fans go to full speed.
old HD7870 GPU works fine. So far I have tried; updating the BIOS, resetting the CMOS, removing all old display drivers, using a different HDMI, removing all hard drives. Even upgraded the PSU from a corsair CX500M to a corsair CX850M. Still no luck.
Are there compatibility issues with the Vostro 430?
Don't quote me but its possible you need an UEFI bios which i'm not sure that computer has. I would probably go with an Nvidia 7xx series or AMD 2xx, maybe 3xx series.
* Are there compatibility issues with the Vostro 430?
Unknown since Dell never tested the R9 Fury on that 2009 system. Is the video card backward compatible to the video card PCIe x16 2.0 slot?
Check the video card for a BIOS switch.
