Windows Server 2008 R2 keeps crashing

Question

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000003b (0x00000000c0000005, 0xfffff8000187a370, 0xfffff88006835a90, 0x0000000000000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 070421-53461-01.

This is the error I get in event viewer each time it crashes. Not sure what is causing it. I have the memory dump file to attach, but file is almost 2 GB at this point.

Hi,
For memory dump, I consider that you could try to use WinDbg previewer tool to check the dump.
You may check some information about image name and stack_txt in dump analysis.
For Windows Server 2008R2 error 0x3b, I suggest that you could check for update firstly, installing new security update could update system file version and fix related issue.
Another, it may be caused corrupt or outdated device drivers. So try to boot into Safe Mode check if it will not crash. Reinstall your device driver just like video card driver.
Then perform a clean boot.
