Nvidia to AMD Display Driver Error

[Bulletproof24]

Hello all.

I recently replaced my EVGA GTX 660 with a Sapphire R9 290 tri-x. It seemed that I had all the appropriate drivers in place after a bit of trial and error, and got the card running fine.
Yesterday I uninstalled all the NVidia drivers, figuring that I wouldn't need them anymore. I shut off my computer and try to turn it on today, and the display driver doesn't seem to be loading so that I can see anything. The computer will boot, go past the Windows loading screen, then the monitor will cycle between not receiving signal and flashing a black screen every few seconds. I am currently running on my backup hard drive, which I cloned for my SSD in February.
I have tried to boot into safe mode (Shift + F8), but I cannot tell if I reach the recovery screen because it does the same thing as when it boots: blank screen and flashes of black.

I have all the AMD drivers installed, the R9 290 is running on the AMD driver, but the display doesn't work when the NVidia drivers aren't installed.

I have also tried copying and pasting the files for the NVidia drivers on the old hard drive into the appropriate folder on the SSD, but this doesn't install them, so it didn't help.

I have already been through this once when first installing the card, and I don't want to roll back to February again. Is there a way to get my display working?

Hardware specs:
Asus Maximus VI motherboard
Sapphire R9 290 tri-x GPU
Intel i7 4770k CPU
4gbx2 Crucial Ballistix RAM


Running Windows 8 Pro

Did you uninstall the old drivers before installing the new ones? I'm not sure if there's any effect if you uninstall afterward, but there might be some lingering files if you do I'd imagine. Someone can correct me on that if that isn't the case.

If your computer is having problems before Windows actually starts, your problem is likely not a driver issue. This may be a stupid question, but is the cable plugged in tightly on both ends?

this is a driver issue since you are able to go past the windows loading screen. it is not till then the Driver is actually loaded.

I suggest IF you can get the screen stable enough to uninstall ALL display drivers and then reinstall the proper AMD driver. Driver fusion is good for this As it will do it all for you. remove Nvidia display and AMD display drivers.

Any time you change a GPU to a different model or brand, Before removing the old card, you need to uninstall the drivers. This go for going from, lets say, 7770 to a 7970, or GTX 660 to a GTX 760, or AMD to a Nvidia anything and vise versa. You need to wipe out all drivers for display and start over. If you have a recovery try this to get you going and then uninstall and reinstall.

I used an extra graphics card I had around to get into my SSD boot. From there, I used Driver Fusion to uninstall all drivers, then uninstalled the driver used by the extra GPU manually. Then I shut down, reinstalled the R9 290, booted, and it automatically found and installed the display driver. I now have catalyst installed and seem to be running fine. Thank you everyone for the advice!

I had this problem and solve it by removing my card GForce GT 630 and remove all DUST from fan and card. Put it back and bingo!! no more error messages. Working great! Also I installed the latest driver.
