Okay, haven't visited this thread in a while. Trying to get my new computer set up to be running this again. I downloaded the regular CPU client and it's working just peachy, but I thought I'd try to run the GPU client as well, and that's proving to be problematic. I keep getting "NANs detected" and it won't run an actual Work Unit. It just shuts down. I tried browsing the forums for a solution but it's all way above my head and I can't make heads or tails of it.

I have an ATI Radeon HD 4350 with 512MB of memory in a PCIe slot. I also have a 4 core processor and 8GB of DDR3, so there's no reason the system shouldn't be able to handle both, that I can see.

In fact, when I launch them both, the CPU version works fine and the GPU version starts running this Test Protein A. Last time this test protein ran for three days before it finally decided to download WUs and then quit on me.
