This one is pretty straight forward... Memory Corruption,, Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder. Boot from the CD, and leave it running for at least 5 passes.

SPTD.sys was noted as well.. Try removing any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads

Special pool has detected memory corruption.  Typically the current thread's
stack backtrace will reveal the guilty party.
Arguments:
Arg1: fffff98005d7ef90, address trying to free
Arg2: fffff98005d7effc, address where bits are corrupted
Arg3: 00000000004f4074, (reserved)
Arg4: 0000000000000024, caller is freeing an address where bytes after the end of the allocation have been overwritten
