OK, forget about it then. I only use that system for crunching so I just told it not to recognize the card. It's a 256MB card and I thought it was on the motherboard at first and was concerned about losing the whole system. In researching temps for it, I did find people talking about screen blanking or thermal cutoff at 110 C. Now that I know it's an actual card, I'll just replace it with something more modern that has good temperature control and uses very little power. Going from 80nm to 28nm is a big step. Apparently, these 8400 gs chips are quite variable and this machine has an overheating chip in it or a bad cooling solution. I also saw mention of some versions of the driver causing the chip to go into thermal runaway. I might even replace the system. It's the original Core 2 quad and isn't upgradable to even a later C2Q. A current Ivy Bridge 22nm Intel I3 could probably match it for about a third the power of a Q6600. Some or all of the Ivy bridge parts can run OpenCL and Haswell is due out later this year which is supposed to have up to a 5x improvement on the graphics, depending on model, and includes the AVX2 extensions with larger FP units on the CPU cores IIRC (could be broadwell that has those). APUs are eating much of the discrete graphics card market. Now that ST_E (sp??) has got FD-SOI working and global foundries has licensed it, expect some improvements from AMD APUs too. Now, if they can just solve the power supply problem for EUV lithography, they'll be set for 10nm and below. It's scary how they power EUV. Think very high powered lasers vaporizing a stream of metal droplets and missing the droplet a lot of the time.
Anyway, since it seems that the chip failing will not take out the motherboard, and most peoples cards are better than mine or have already been replaced, don't worry about it.
