BSODs once a day or so with the high-end Windows 7 64-bit boxes.

More often, if they try to run backups with them.

Yes, diagnostics have been run, etc.

Microsoft has problems with the permutations and the qualifications and all the anti-malware stuff, unfortunately; they're phenomenal with dealing with all that, and phenomenal is just holding even with the complexity they have to deal with.

Most often BSODs are caused by third party device drivers.

Solution: Eliminate third-party drivers.

Apple solved this problem years ago.

I have what I consider to be a high end Windows 7 x64 box and it performs great regardless of it I'm running it natively or in my VM. Never had any BSODs.

The only time I've seen BSODs on Windows 7 was after it had 6 viruses and I had to clean it all up.
