Random, repeated BSODs when doing practically anything.

Hello again, Sevenforums help team!

In my last post, in which errors of a similar nature were occuring, (visible here), my computer simply died. Since that time, I've replaced the power supply, and had the motherboard RMA'd. I thought it would be the necessary fresh start that I needed to remedy the problems, but the BSODs are back, and with much greater frequency. In fact, I'm forced to upload the .rar file from my laptop, as attempting to open Google Chrome on the plagued computer caused another crash.

I should note that I'm entirely unsure of what sort of error is causing this, as they seem random - sometimes they happen when I'm opening a program, other times, they just pop out of nowhere. One trend I did seem to notice, however, is that flash plug-ins, applications, and other programs crash constantly before the computer shuts itself down.

I've been told it could be the memory sticks that I'm using, but after running memtest on the individual sticks for at least 3 passes each, I'm not sure.

As always, any help would be greatly appreciated.

Being that it was a 650W Corsair PSU (meaning, either the TX650, TX650 V2, HX650, or even the AX650), it was definitely not caused by the PSU unless it was brand new and also defective.

What PSU did you replace it with? Make and model?

The PSU that was thought to possibly be a cause of the previous crashes was RMA'd, and Corsair sent a brand new TX650, which is now installed in the problem machine.

Ok, good, so you didn't have to replace it with a low-quality unit.

Can you RMA the motherboard to see if it's the motherboard?

The motherboard was just returned from its RMA at Gigabyte. It was tested to be in working condition.

Damn. How about the CPU?

I'm unsure if the CPU is the cause. I'm hoping someone can take a look at the logs I posted and help me thin down the options.

Bump. Issue still unresolved.
