BSOD in Enterprise x64, multiple causes?

I would suggest leaving it as is and collecting a few dump files to see if we can see if there's a pattern there. The point here is to get a couple of dump files where the system hasn't been changed - then the pattern may be easier to see.

For example, a game can issue commands to the hard drive, the video, the audio, etc - so if the game is causing issues all of these may show up as "causes" for the crash.

Both blue screens point to a system service causing the issues - the first one because of the bottom 2 lines in the stack text (which are the first and second one's - as the stack is read from bottom up):

Code:

fffff880`05127d40 fffff800`02aa4486 : fffff800`02c3ee80 fffffa80`05523b60 fffff800`02c4cc40 fffff880`01022534 : nt!PspSystemThreadStartup+0x5a
fffff880`05127d80 00000000`00000000 : fffff880`05128000 fffff880`05122000 fffff880`05127690 00000000`00000000 : nt!KxStartSystemThread+0x16

And the second one due to the name of the error: SYSTEM_SERVICE_EXCEPTION

In addition to this, please generate the following reports, zip them up and upload them with your next post (including any subsequent dump files):
- Go to Start and type in "perfmon /report" (without the quotes) and press Enter. Save the report as an .html file
- Go to Start and type in "msinfo32" (without the quotes) and press Enter. Save the report as an .nfo file

"If it ain't broke, don't fix it!" :)

Nothing noteable in the error messages - with the exception of some GTAIV.exe errors. But they may/may not be related - just let things be and see if there's further issues.
