To add, I just ran WhoCrashed and got this:
On Fri 10/03/2017 21:45:17 your computer crashed
crash dump file: C:\WINDOWS\memory.dmp
This was probably caused by the following module: mwac.sys (mwac+0x6C8A)
Bugcheck code: 0x19 (0x20, 0xFFFFAB8A5CF90D00, 0xFFFFAB8A5CF90D20, 0x40200D0)
Error: BAD_POOL_HEADER file path: C:\WINDOWS\system32\drivers\mwac.sys
product: Malwarebytes Web Protection company: Malwarebytes description: Malwarebytes Web Protection
Bug check description: This indicates that a pool header is corrupt.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules. This problem might also be caused because of overheating (thermal issue).
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: mwac.sys (Malwarebytes Web Protection, Malwarebytes).
