I have a quad core q6600 wigh 4gb ram and an nvidia gforce 8600 gt with 512 mb ram. I recently updated the bionic application to 6.4.5 and attempted to crunch the new CUDA wu's. I downloaded them and after running just one for 21 seconds, my computer screen goes black for about 1 sec. Then my screen gets all pixelated and the computer locks up, sometimes forcing me to hit the restart button. This has not ever happened before, as I used to crunch 4 regular Seti wu's at a time. I went to this website http://www.nvidia.com/object/cuda_get.html?CMP=KNC-CUD-K-GOOG&gclid=CLTc9Yvb85cCFQQCagodpGhwCw to download CUDA 2.1, and still get the same result. Does anyone else have the same problem?

Snow on the screen ?
