I get occasional BSOD on startup. I ran Who Crashed and this is the result
Crash dump directory: C:\Windows\Minidump
Crash dumps are enabled on your computer.

This was probably caused by the following module: aswsp.sys (aswSP+0x44640)
Bugcheck code: 0xE3 (0xFFFFF880048FE640, 0xFFFFFA80088D6040, 0x0, 0x2)
Error: RESOURCE_NOT_OWNED

Bug check description: This indicates that a thread tried to release a resource it did not own.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
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: aswsp.sys (avast! self protection module, AVAST Software).

One thing that finally dawned on me these seem to occur when I close windows/browsers and immediately click Shut Down system. If I wait a min or so it doesn’t seem to happen. Last night I had some folders open editing photos and just closed everything and clicked shutdown. I got the BSOD on bootup this morning. The last one was over one month ago.
