Radeon x1950 fullscreen failure after vista upgrade

By welshboi82 ·
Well, I'm tired of dealing with Dell on this issue so thought I would ask some people that seem to know what they are doing.

I decided to give in and upgrade to vista (after the disc sitting on my shelf for months) and am now having a problem with my Radeon x1950 Crossfire (though I am not running it in crossfire mode at the moment, it doesn't solve the problem by switching it on either...before you ask ).

I have a Dell XPS710. The problem is thus, when I try to run anything in full-screen (such as a game or windows media center) the screen just flashes between a black blank screen and the program itself. But am unable to use the program.

When I go to the task manager I can see the program in the background without it blinking, but when I try to click on the program it starts blinking again. It happens in all screen resolutions.

I've tried the latest dell drivers and the latest ATI drivers and have the same problem. I've tried a combination of the Dell video driver and the ATI catalyst program and vice-versa to no result.

The only time I got it to work was the first time I installed the Dell Drivers, it worked great, until I rebooted and the problem returned.

There are no device conflicts listed in the device manager and my bios drivers are up to date.

I include below some of the contents of dxdiag to make it easier for you to get an idea of my setup. Any help to get my video card working would be most appreciated.

Just a thought...

You say you've used combinations of Dell and Catalyst drivers. I just wondered if you'd checked for the latest 'Vista ATI' drivers?

If not, try this link:


It might help.

Yes, I have tried both Dell and ATI drivers already.

I said 'Vista' drivers...

by OldER Mycroft In reply to Yes

Not ATI drivers - Vista ATI drivers.

Oh, sorry hehe

Misread your original reply. Downloading them now, should they really be 88mb? Seems harsh for a driver.

Re. Radeon x1950 fullscreen failure

I am going to have a guess and say that the "direct X" might be at fault here, you might have more than one "Direct X" on your system. Try and delete the "Direct X" and re-install, or downgrade to "Direct X 9" (if possible). I hope this works for you. Please post back if you have more problems.

Did you find a solution yet?

by ejdavis In reply to Radeon x1950 fullscreen f ...

Wow have you found a solution yet? I've got the exact same problem.

When in windows or playing a game I will get an intermittent black screen and then back to what I am doing. I have an ATI X1950XTX Crossfire installed with an ATI X1950XTX. I get the same problem when I turn crossfire off. I've even tried restoring my original ghost image (clean vista install) to see if it fixed the problem but with no luck. I have never overclocked these and they are only 2 months old. Catalyst Centre says they are running at 67 degrees. They are connected to a Dell Ultra Sharp 1908FP DVI monitor tried at 60/70/75Hz refresh rate.

I have a complete ATI certified system.

Vista Business
Core2 E6600
ASUS P5W DH Deluxe
1x ATI X1950XTX Crossfire
1x ATI X1950XTX
2GB DDR2 1066Mhz Ram
Enermax ATI Crossfire Certified Power Supply 650Watts
Antec P180 ATI Crossfire Certified Cooling Case

ATI support gave me the stupidest things to try I guess I'll try sending the Mastercard back under warranty because I can't see it being software or drivers.

I am experiencing the same thing...

by rainmaker In reply to Radeon x1950 fullscreen f ...

I have a new single Powercolor X1950 Pro 512MB AGP card, using Catalyst 7.7 drivers on XP Pro SP2. It's been working fine for about a week. The PSU is also new, Cooler Master Extreme Power Duo 600W (dual 12V rails, 18A each). The card is powered by one of the 6-pin PCIe plugs. Last night, all of a sudden, it started doing this blank screen thing, during full screen video playback, and also when in Half-Life 2, strangely, usually during the loading screens - the game itself did play OK except for one or two blank outs I think. Typically it will blank out, then return, blank, return, blank, return etc. Once it hung completely and I had to reboot. Very frustrating since it's brand new. I don't think it's the drivers because if I recall correctly, it blanked out during a Ghost session (i.e. DOS). And I would have thought the PSU was adequate. Any ideas?

Not an easy solution

by ejdavis In reply to I am experiencing the sam ...

Well I broke down and ended up contacting ATI support via: http://support.ati.com/ics/support/default.asp?deptID=894
A tech replied to my post (about 2 hours) much quicker than I thought and said to send my card back to ATI for warranty right away for a replacement because it was a hardware related issue. I wasn't too keen on paying for the shipping to send the card but they paid the return trip and replaced my card with a brand new one within approx 1 day. If your card is under store purchased warranty take it back, otherwise I think you'll have to end up shipping it away like I did. Good Luck.
