Have a look at your system timer watch-dog parameter.
This may help!
I forgot to say that not only everything goes black, the problem is also, that the graphic card restarts itself (I always get the "report crash" pop-up window), and also I get no results after computation (just zeros). Do you think, that this has something to do with the timer? Sorry for a stupid question, but how can I change the watch-dog timer? Thanks.
Hi Pisoir
I went to similar issues a couple of months ago. My recommendation:
(1) Just make sure than having increased the size of your computation, doesn’t lead to a watchdog situation where the OS is worrying about the GPU not responding and so merely decides to reset it.
In this case, just expand the timer duration appropriately.
If you’re under Vista, have a look at http://forums.amd.com/devforum/messageview.cfm?catid=328&threadid=100142&highlight_key=y
(2) If (1) is not fixing the issue, then I’m afraid you’ve entered into a situation I met where a multi-loop in Brook generates crashes and blue-screen (see http://forums.amd.com/devforum/messageview.cfm?catid=328&threadid=104937&highlight_key=y )
At this point I’m still expecting some feedback from AMD developers about this bug.
Being stuck on (2) I moved from Brook+ to CAL and as of today I’m barely seeing this phenomenon happening (even if from time to time it shows up and crashes the PC).
Good luck and let us know how it worked out for you

Thank you for your advice. I have Win XP, so I'm not sure if the proposed solution for vista also works for win XP. I tried it anyway (add TdrLevel in win registry), but with no success. I couldn't find any explicit solution for win xp, so if you know how to set this timer in win xp, please let me know. Thank you once more.
