EPIC FAIL: System.OutOfMemoryException: Out of memory

It’s a long shot but check out these issues I had over the last 9 months I had the same crash occur twice.

Chances are that this happened due to faulty RAM. Run Memcheck86+. Take note that it took me 18 passes to find the error, though. It was very subtle. It is very unlikely, this is your issue though. But why not let Memtest86+ run over night, I can see no reason why not to.
