Multiple BSoDs - 0x50, 0x1A, 0x19

I know it's an older system, so I might be dealing with a motherboard level impending failure here, but I figured I'd run it all by another set of eyes before declaring the thing a lost cause.

Recent history:
Upgraded to a 64 bit version of windows from 32 bit in order to install and use more RAM. Post install, I found out the RAID had failed (not sure what happened, nothing in the BIOS was changed, but it reset itself from RAID to IDE at some point before the install). Set up RAID, installed again, it dumped itself off RAID and pretty much deleted the entirety of one of the two drives. Gave up on RAID, got a new HDD, backing up to a Synology drive instead. Got hit by that MS KB3004394 update that caused a whole bunch of problems during update installation in the new HDD. Worked through that, things were stable for a while. The past two weeks, I've had a host of issues and BSoDs and I'm at the limit of my expertise.. Posting my Log Collector file with the relevant dumps/event log per the BSoD instructions. There's a bunch of other troubling stuff in the event log too..

Done already:
**ChkDsk passed, drive is brand spankin new, no problems there.
**Memtest passed a month ago. The initial RAM upgrade gave me two bad sticks. Those were replaced, memtest passed when I double checked to make sure the new ones were good.
**SFC /scannow found no problems
**The VSS issues seemed to have stopped since disabling System Protection and deleting all the old restore points. I still have it disabled. The one BSoD I know happened overnight (1 Feb 2015) when the weekly backup was supposed to happen so I have to assume those were related. Pretty sure that was the cause of the STOP 0x19.
**Ran a full antivirus (Avast) scan and a MBAM scan. Both ran clean this morning.

Here for help! Willing to repeat tests/checks if necessary. Let me know if you need any other info - I have the system specs filled out in my profile already, or at least the important bits of info. If I'm missing something or you need more detail, please ask and I'll do my best.
