I have not tried another miner yet, I will add that to the troubleshooting list.

I did try the cards individually/risers individually, adding them in one at a time.  The issue starts on anything higher than 1 card.

I'll leave the system up for a while just to see if there are any issues.  So far the only time it has failed is when it is mining.

I'll try turning on the integrated graphics as well.



Thanks for the page file suggestion, I'll give that a shot.
