BSOD/ Post login System Hang/ Explorer.exe Crash

Hey, New here, had this problem for quite a while (been using win7 for over a year with this hardware setup.)

Well so basically, a few weeks after a fresh install (reformat every 3-4 months usually just a personal preference), it starts to hang after logging in. It happens anywhere from 10-45 seconds after entering my password. I don't have much of anything on start-up because I prefer to have it start-up and choose which programs I want to run when..well you get the picture, anyways. So it hangs occasionally, not every time, I would say probably 30-40% of the time. Well recently it crashed, gave me the BSOD. I have the crash dump file I'll attach here. From what it looks like to me, it has something partially to do with my processor. Maybe my chipset, i'm not sure, which is why I'm posting here. I feel like both these problems are related. I'll also include the events the day of it BSOD. If you need more information let me know.

System Information:
Asus m4n98td EVO mobo
AMD Phenom II 955be (not overclocked)
8gb ram Corsair XMS3 1333mhz dual channel
Asus nVidia ENGTX 560ti 1gb OC edition
Western Digital Blue 320gb hdd
Western Digital Green 500gb hdd


Now, tbh, I'm just plain puzzled at this point, it never BSOD before, I did lose power the other day, but I ran all the hdd, ram, cpu, vga integrity tests i have and they all ran through fine. Its about time for a reformat, but I would like to see if I can solve this problem.

Thank you for looking, I appreciate whatever feedback you can offer.

....no one?

Bump

Reformatted. Nothing installed but drivers, and it BSOD of death again.

Bugcheck error 0x00000050

From what I can find it seems to be a hardware error, specifically with either my ram or my hard drive. I ran Memtest and chkdsk already.

Help would greatly appreciated.

Did it again, heres the minidump...had the same bugcheck error in event viewer ie --> 0x00000050

okay, well I ran it on all 4 at once, it amassed something like 2000000 errors and then stalled. Wouldnt complete one pass, so I just went and ran 2 passes on the first stick I tested alone and passed with no errors, then I went to the next stick, and it stalled at like 300000 errors, and wouldnt complete a pass. the rest of the sticks ran fine. I took a working stick and ran it through slot 2 and it passed fine. So I'm determining that stick 2 is dead since I doubt that it can be repaired. Unless theres a way I'll just run with 3 sticks until I can upgrade my ram

Tested the dead stick in two other slots, same result.
Tested all sticks in separate slots, no problems except with the dead stick.
I'll keep this post open just in case something else happens, otherwise I'll mark it solved in a day or two.
