MY system seems to be blue screeing duing back up. I typically use Norton Ghost 12.0. But to test whether it has something to do with the software, I also used Apricorn EZ gig. The crashing seems to have increased after installing a new hard dirve. I went from a 80 Gig to a 250 gig hard drive. The images I used was a direct copy of the old drive to the new one.
