Anyone still having this problem give this a try.
I have slowed down my memory timings namely Row Cycle time 14 and Row Refresh cycle time 18.
This is not an overclocking issue as, Prime 95, memory test 86 and other OSs all run fine.
Having done this I have been connected to the internet for last twenty four hours. No probs so far and still going.
I'm wondering if this could be an issue that is causing more than this problem alone.
I know that memory timings on AMD chips need to have slacker latency than Intel and wonder if this is where the problem lies. Might explain some of those other random crashes and install failures that people can't work out.

Would like to know if this has successful results for anyone.
