Have had a few black screens as well. Have now gone back to my trusty silverstone 850w, only reason I changed to the corsair was because I thought the silverstone was getting a bit too warm in operation.

This morning 2gb of my main memory has dissapeared - yet I fully tested it for nearly six hours the other day with memtest - all ok.

Oh well the diagnosing continues......

your doing all the right things - switch out components to isolate which one is the problem. think back to what all you have changed since the problem appeared - or is this a new build?
