BSOD Memory Management Error, didn't catch error code.

Mate, if you want to have another test round before going to swap hardware components, try Driver Verifier once again.

The last crash dump reads almost as usual, and nothing more helpful info is contained in it

OK Arc, thanks for all the help. I'll order some new RAM in the coming days and see how that helps out the rig. If it's still messed up I'll spring for a new motherboard. In your experience, what are the most reliable boards?

Again, thanks for all the help, and I hope I don't have these issues with the new hardware!

About the boards, opinions differ.

I think gigabyte is good. Some hardware enthusiasts say it is Asus.

You may take any reliable brand. Choose the features based on your needs.
