Multiple BSODs over the month, no clear root cause

BlueCanary · 30 Oct 2013

I built this computer about a year ago, and I've had BSODs every one or two weeks for just as long. The problem is that I've never been able to tie them to one program, one driver, or one piece of hardware. All of the diagnostics and general health checks I've run on the system and its hardware come out clean.

Usually the BSODs are far enough apart that I forget about them until the next one comes up, but I've had three or four in the last week alone. Virus scanner shows nothing, and the dump reports through BlueScreenView remain unhelpful because all of the drivers involved seem to be essential system drivers and processes. There's got to be something behind all this, but I can't figure out what. Any suggestions?

Thanks! I'll run through all these steps in the morning and get back to you. One catches my eye, though-- why Microsoft Security over Avast? I've always heard Avast recommend over MS security because Avast offers greater levels of protection under its free plan.
