Hi PS. Sorry mate, that doesn't work. I've even tried using older versions of their drivers without luck. You are right, it's a driver issue, not a hardware one. But it's the driver that's not working with the hardware. 
The ATI drivers are NOT top-notch these days however. I've visited dozens of forums trying to find help on my isssues and I'm not alone unfortunately.
To reformat my machine is like chopping off my arm to fix a cut on my finger. I've spend about 40 hours now trying to get this card to work right and I'm running out of patience.
Problem is, this card should just WORK. Every NVIDIA card I've had did. Plug it in, load drivers. Go play games. Simple thinking right. With ATI it's, plug in drivers, experience hardware failes, spend hours fixing hardware failures from ATI card, play games, find new problems. Uninstall & reinstall drivers, different drivers, different card settings, change AGP settings, change voltage. I've had enough.
As a result I'm selling my ATI card and will probably never buy another ATI product again as long as I own a computer. Pity, this card when it worked ROCKED. 
Thanks all for your help.

Bummer to hear that. But if you aren't willing to wipe the slate clean, maybe you should stick to consoles. Blankly blaming a companies drivers for your problems seems to miss the mark. The problem may well be some old Nvidia driver files you've been unable to rid your computer of, or some funky tweaking gone awry. Have you run some Det. Destroyer, and some other clean-up programs? Or any other video- card or help forums? If you're going to use different GPU hardware often, it would be a good idea to know how to fully remove many of the leftover .inf files both ATI and Nvidia leave behind.
On another note- it sounds like you're woe-fully unprepared for a hard-drive crash. If re-formatting seems like too much of a pain now, and spending FORTY HOURS trying to get a video card working is a better option than re-formatting, I STRONGLY suggest you start making some back-ups. Your hard drive WILL crash, it's only a matter of when. Additionally, it makes re-formatting, and re-installing your programs and O/S a relative breeze. Better to be prepared for when it happens. And it will make cleaning out corrupted files a relative breeze.
And, yes, there are still the uneducated masses who will still say ATI's drivers are not up to par, relying on truths of 2-3 years ago, but these are generally the same folks who wouldn't know an .inf from .dll, and beleived that the NV30 was going to handily outperform the R9700. Fact is, ATI's drivers for the R9700 are as good, and IMO much better than Nvidia's latest generation drivers. Of course, they should be, since the R3X core has been out nearly a year now, while Nvidia has not had much time w/ its Nv3x line-up.
Anyway- do you need links to some good Nvidia driver removal programs, or have you alredy tried that?
