>I'm not sure. One was mentioned on ScottGu's msdn blog, and it was a crash-related patch. I believe he said it would be included in a VS2010 update (which is separate from a Windows update -- you can check from within VS).
I am at the computer store right now. As soon as we started to switch the RAM with another brand, all errors went away with MemTest86. Right now, we have 4 slots of RAM in there and the test went ok.
We are doing additional tests to make sure that all will be ok up to 100%. I will also check the updates for VS. BTW, MemTest86 recognizes the new memory. The other ones were not recognizable by MemTest86.
