Briefly, it all started by pre-ordering the nMP in December of last year. I received the unit and after some time, I had graphical corruption issues. I would get random flashes of graphics pop ins. Returned. Next, I received my nMP in April. I had a major crash issue where the system would go to sleep, but would shut down and not wake up. This happened multiple times. Returned. This last time, I got another nMP on Monday, and I am now having the same exact issue as the second one. It will randomly shut off in the middle of the night after going to sleep. I will wake up and it's off. Looking at the crash log, it looks different than my previous nMP. I was thinking if it's anything that I'm doing. However, I have my 2008 MP still on and connected to the same power strip and after 6 years of use, I've had 2 crashes, but nothing like this. It's still on right next to me, where the nMP had to powered on. Has anyone experienced anything like this? The configurations have been the same, except the first one was a D300 and the subsequent two have been D700. The processors and RAM (6-core/32), have been the same. I don't think I have a choice but to return it. A system this expensive shouldn't give me these issues.
