BSOD when installing Windows Updates (also other times)

[chufmoney]

I have service pack 1 with Windows 7 Ultimate x64. I thought it was my PSU previously, so I replaced that after it burnt out my old mobo. I've now replaced my mobo and have checked that my PSU is outputting the right voltages. I'm still experiencing blue screens, typically when I'm installing programs. Ran Memtest for multiple cycles with each stick of RAM and it checked out fine. .DMP files included as well as performance check.

Any help is super appreciated, been a frustrating few months as I replace part after part.

It's looking like your other hardware failures may have had a negative impact on your ram.
The bsod quotes a memory management error.
I would check it by running memtest overnight. (unless it immediately starts spitting out errors then you know right away.)
