Windows 7: BSOD no particular reason

Windows 7 Home Premium x64
BSOD no particular reason

There's no action that seems to prompt the BSOD, and I'm not running at full capacity. I've attached the file from the DM Log collector.

Memtest86+ - Advanced Memory Diagnostic Tool

Which one should I download?

You have two options to choose from, you can either download the ISO version then burn it do a CD and boot it from there.
The other option is downloading the auto installer for USB sticks, you then boot from that USB stick.
Be warned though, it will format your USB then install the files needed to make it bootable so any files left over will be wiped off.

So how does it work?

It works by writing a series of test patterns to most memory addresses over 9 tests, it then reads the data back to compare it for errors.

The default pass does 9 different tests varying in access patterns and test data. A tenth pass is optional from the menu which writes all the memory in zeroes then sleeps for 90 minutes and compares it to see if any address have changed, this takes 3 hours per pass each time.

My memtest86 isn't booting! What should I do?

This can be caused by a number of different reasons, common ones include your BIOS not setting using the correct settings, you might want to change your boot priority order.
Other causes include your motherboard not supporting bootable USB sticks in which case you'll need to use a CD (or floppy drive).

Windows 7 Home Premium x64

so i ran memtest and got a couple hundred thousand errors. i'm planning on RMA'ing my memory now, but before i do, should i look into other parts of my computer? I RMA'ed my mobo, memory, and psu several months back because of problems that could have been linked to one or multiple parts, and seeing as my memory looks shoddy again, i'm wondering if there are other concerns. Thanks for the help!

I would test each RAM stick in different DIMM slots to make sure it's your RAM and not the motherboard.

sorry for my ignorance and thanks for your patience!

If memtest detected errors in each of the memory/DIMM slot combination tests, is there anyway to differentiate whether it's a result of bad memory sticks or bad mobo? Also, I ran the windows memory diagnostic tool, which I know isnt as thorough, but it turned up zero errors so now I'm slightly befuddled cause given the extensive number of errors memtest reported, I would have, perhaps incorrectly, expected another memory test to at least report some errors.

Although Windows Memory Diagnostic is inferior memtest86 can still report false positives, try memtest86+ if you aren't running it.
If you are then I would replace the RAM.
