Server keeps blue screening, even after lots of successful testing

[BondUniverse]

I have a custom built server that just LOVES to crash. I've rebuilt it several times and even changed out a lot of the hardware, still it continues to frequently crash... I've also run several different hardware diagnostics and burnin software (PCI board based), but it never seems to have an issue with these... Starting to think it might be a driver, but I don't even know where to begin there...

I'm trying to start playing around with the Dump logs, but I've never really looked at them before, so I don't exactly know what I'm doing...

I ran DumpChk, and here is the analysis... Any ideas?
