I recently bought the latest and "best" Dell XPS 15 with preinstalled Windows 8.1. In the two weeks I am using it now, there have been a lot of application crashes, unexpected system shutdowns and also some BSODs.
Then, sometimes I can work for hours without any visible problems...
What I already tried/did: I am using the latest drivers provided by Dell, did a system checkup (HDD, Memory) using Dell and Windows tools - without any clue. System fans are off or low, so I wouldn't guess it's a thermal problem.
Although both DELL checkup utitlites didn't find memory problems any more, a short test with memtest86 revealed a lot of problems. After exchanging RAM in one slot, the memory errors were gone and I believe that all of the problems described above will not occur any more.
