    UPDATE: problem has been solved after rolling down to 9.5 (at least no crashes so far after some minor testing). Thanks to all those that helped. I guess I was too used to the nvidia drivers which never actually gave me any problems, only performance differences. Didn't think changing drivers would help at all! Hope this can help someone else as well.


    Hello. I recently purchased a Powercolor HD 4850 that is not using the stock reference design. It can be located here. The problem I am having with it is fairly strange. I have tried both Windows 7 RC1 build 7100 64bit and XP professional with sp3 and the problem occurs in both settings. I can play any 3d games fine as long as it is in full screen mode. However, I have problems with having anything 3d in windowed mode. folding@home's 3d view, Crysis/L4D running in windowed mode, or even Aero in Windows 7 will frequently crash my video driver. If in xp, it may produce some artifacts on the screen like when you overclocked too much when the driver crashes. The temperature of the card is relatively low. GPU-Z reports 61c for the card temp with 61-63c for the core, shader, and memory. I would like to know if there is anything I can do to remedy the problem. Is it a hardware issue? Driver? Or perhaps even bios? I am not sure why it would work flawlessly in 3d mode while have problems with 3d on 2d. By the way, the card idles at 500/993 at 1.05v (voltage according to hardware monitor). Thanks for anyone who can help me out with this strange problem.

    since fullscreen is fine, id say its either the fan not spinning up in windowed mode (try forcing it in CCC overdrive) or a driver bug.

    Cant say i run anything in 2D to test it, and since i upgraded my cooling it wouldnt help to test anyway.

    I've monitored my temperature with gpu-z while running in none full screen mode and the temperature never goes over 6xc and fan speed does increase along with the temperature. It just stuck me from reading here that it may be a problem with 9.6, as that's the version I've used on all the operating systems. I thought since it was a stable release it shouldn't be the problem but I may have to try out an older build or the beta (if someone can provide me with some hints on where to look for those, it would be very helpful). Do you have a driver version that's fairly stable and trouble free to recommend? Thanks a lot for the quick and helpful response.

    If you could fill out your system specs in "User CP"...it will help everyone help you better.


    Thanks and Welcome:)

    9.7 beta are here on the forum, you can search for them.

    You could always google for cat 9.5 - they were trouble free for me.
