Sapphire 6950s / catalyst 11.6 - computer freezes when I watch video

[AlexWaters]

I have this problem where my computer freezes when I watch a video. It only happens when I am mining on both of my Sapphire 6950s. I have tried re-installing all of the drivers / catalyst - and I used driver sweeper.

I have tried resetting my cards to their default clock settings - doesn't fix it.

If I am mining on both cards, and click on a video (on youtube or whatever) - the computer instantly freezes, and I have to restart it.

Anyone else have this problem, or know how to fix it?

Try disabling hardware acceleration for flash (right click on the video, settings, leftmost tab) if you haven't already.

That sounds bad. I'd disable Crossfire and try it on one card at a time and see if it still happens. You shouldn't get a lockup like that.

A lot of people get issues like this if they have -f1, try running at like -25 or -f50 for videos.  I can game and mine if it at about -f60-75 easily.  You drop a few hash but can use the pc.

I have the same problem using 64-bit Vista - OP, are you on 32 or 64 bit?

Flags (-f <high>) don't seem to make a difference.

Videos cause an instant lockup, so does opening GPU-Z or CCC while mining. (They open just fine if guiminer is stopped.)

The -f flags do nothing - but disabling hardware acceleration on the flash menu seems to have worked. I also disabled all of the options on the video section in catalyst - maybe that helped too.

Thanks guys! Now I can watch my youtubes
