Ati 4850 problems

Hi,

I recently installed RTM Windows 7 Pro. Before i had 7000,7056 and 7100. On 7000 and at 7056 i've had similar problem i have now. When i try to refresh my Windows Experience Index my screen goes black with colour boxes and i have to restart computer. Screen goes black when windows try to test Graphics 3D performance. I experienced it in some games too, it happens when graphic card tries to change mode from 2d to 3d (when screen is blinking after entering game). Earlier, after clean 7100 install i did't have that problems. I don't think thats my PSU problem, because i'm playing many new games and computer is working fine. As i said it only happens when graphic card is changing modes. System is 64 bit, i have newest 9.10 catalyst drivers. Graphic card is Radeon 4850 Gainward Golden Sample.

Any solutions?

Try to locate a driver for your monitor(s) and install. Probably won't help. Can't hurt.

Sadly it didn't help. Here's what happens when i try to refresh index:

I see what you're saying.

I don't like the looks of that, even if it only happens very briefly. Might mean failed or failing component on the card. That is the type of distortion that can happen in that case. I had something similar on an NVidia 6200A-LE with blown capacitors. I replaced them and card is still functioning well today.

If it is still within warranty, show that picture to the vendor of your particular card. Perhaps they will agree to an RMA and you will receive a new card.

You've got nothing to lose by trying except a little time writing brief, friendly e-mails to them or whatnot.

Good luck. Please let us know if you do this, because I'm very curious as to what they would say and do about it.

Thanks for fast reply. Yes, it's still within warrantly. I was thinking about that, but firstly i have to check card under other system, because sending card to repair means that i will be 2-3 weeks without my main computer. In that case i'll install Vista 64-bit today or tommorow. I'll tell you how's my Radeon under vista.

In some instances, you can provide a credit card number to them as colaterral. They will send you a new unit immediately. Once they receive the one you send them, they no longer hold your card info as colaterral.

You could ask them to do this for you, if they in fact, agree to RMA and your testing fails.
