I think the first thing to do if not done already is to run a complete 
memory diagnostic. I would wait on swapping out memory. Normally a 
memory diagnostic will generally uncover memory issues. Sometimes bad 
memory can cause some very weird things to occur.  Both Mother Boards 
and power supplies can cause some problems. In my experience a long time 
ago, I had a relatively new system that had some intermittent issues. I 
brought it back to the place I bought it, and it ended up to be a mother 
board. More recently I had some very strange issues, such as hard drives 
going offline unexpectedly. I reseated and replaced the cables which 
made a difference for a while, and I finally replaced the power supply 
and that made all the difference in the world.
