BSOD with ntoskrnl. Multiple codes but same source

I've been having random BSOD and although I suspect the Logitech USB mic is part of it, it seems to happen out of nowhere with bug codes like 0x00000019, 0x000000a, 0x0000018, and 0x000001e. It can happy a few times a day and it's getting really frustrating trying to figure this out. I am sure I updated all of my drivers, and I was wondering if anyone could help pinpoint exactly what is really causing it.

Code:

*                        Bugcheck Analysis                                    *

Use !analyze -v to get detailed debugging information.

BugCheck A, {28, 2, 0, fffff800032d6cd0}

Probably caused by : memory_corruption ( nt!MiFindNodeOrParent+0 )

Lets check RAM first. Run a minimum of 8 consecutive passes, preferably overnight, or until errors occur using MemTest86+.
