AMD Radeon HD 6670 Drivers keep reverting back to Standard VGA after restart.

Hello, Tom's Hardware community,

I have been recently installed the AMD Radeon HD 6670 graphics card. I followed the usual recommended procedures to accomplish this. This included uninstalling all old drivers, installing the video card and hooking up the VGA cable directly into the card, and installing new drivers. I am able to get the card detected in device manager and it is fully functional.

The problem is that every time I shut down my computer and turn it back on the card is no longer detected. Furthermore, I have to plug the VGA cable back into the standard video port because apparently the computer has completely forgotten about the new graphics card. When I check device manager, the Radeon 6670 is no longer detected and instead the computer has switched back to the Standard VGA settings. I am a complete amateur at these kinds of things and I am clueless on how to fix this issue.

Any help would be much appreciated. If there is any information that I have left out that could be useful please inform me and I'll try to provide it.

Might want to go into your bios and make sure it doesn't default to integrated gpu, onboard video, or anythng that sounds like that, and instead it is defaulted to PCI-E or discrete.

I believe I have already checked my bios. The initial video display is listed as PCI-E 16x, which is where the video card is installed.

Uninstall all driver's by going into safe mode. Then turn off the computer and put the card in a different PCI-E slot. Boot into safe mode again, and re-install the AMD driver's. It should be 12.6, if you have issues with that version, use the 12.7 BETA drivers.

Unfortunately, my motherboard is rather outdated and I only have one available PCI-E slot. To make matters worse I am unable to uninstall or install drivers in safe mode. The system keeps telling me it cannot gather system specifications.

I see.

What is the brand and model of it? Also if possible can you list out the specs?

Well, the motherboard brand is Dell and its model is 0K071D. By specs, what specifically are you looking for?

Mainly the motherboard, CPU, PSU.

Well, the CPU is a horrid AMD Athlon 64 X2 5200+.
The PSU is an Antec 500w.

Well, since you have an AMD chip, I don't want to mess up any drivers associated with it.

Anyways, what you can do is try older legacy versions.

Try the 12.4 or 12.3 versions for your operating system here. Make sure you uninstall all previous drivers before installing new ones.

If you have vista or win 7:

If you have XP 32 or 64 bit:

Thank you, I'll give this a shot and see how it goes. I'll provide an update on the results once I'm done.

You can also try using Driver Sweeper to uninstall older drivers, then reboot, then you should be able to install the latest. Driver Sweeper can be used for both the GPU and mobo chipset drivers.

No, I don't suggest that at all, being that OP has an AMD chipset. Using driver sweeper will wipe drivers related to any AMD driver. Highly not suggested El Tigre.
