Random Blue Screen/Freezing

Hi, I'm running

CPU: AMD FX-8320
Motherboard: ASUS M5A99X EVO R2.0
CPU Cooler: Cooler Master Hyper 212 EVO
RAM: G.SKILL Ares Series 8GB (2x4GB) DDR3-1600
GPU: MSI Radeon HD 7770 GHz Edition

I've overclocked my CPU using the http://www.overclock.net/t/1348623/amd-bulldozer-and-pi... guide

My current BIOS Settings are the same as in the recommended settings of the guide. (It's on the second post)

But for people who are too lazy to click the link,
Ai Overclock Tuner - Manual
AMD Turbo CORE Technology - Disabled
DRAM 1600Mhz @ 1.5v
CPU/NB Frequency - 2200Mhz
HT Link Speed - 2600Mhz
CPU & NB Voltage - Manual Mode
CPU/NB Manual Voltage - Set between 1.25v-1.3v (Increases stability for high overclocks)
CPU LLC - Ultra High (75%)
CPU/NB LLC - Auto
CPU Current Capability - 130%
CPU/NB Current Capability - 130%
DRAM Current Capability 130%
Cool'n'Quiet - Disabled
C1E - Disabled
SVM - Disabled unless running Virtual Machines
Core C6 State - Disabled
HPC Mode - Enabled (Some motherboards this has caused freezing so keep that in mind)
Amp Master Mode - Disabled
***The power saving features should be disabled until you find your stable overclock. Then feel free to re-enable them to benefit from power savings

While I'm following this, I've also disabled my CPU Spread Spectrum and PCIe Spread Spectrum due to the posts in the thread (6th and 7th post).

My CPU Ratio(Multiplier) is at 20
My CPU Bus Frequency is at 200
My CPU Voltage is at 1.375v
My CPU/NB Manual Voltage is at 1.275v

The weird thing is, I don't know if it's unstable or not because of low voltage or just bad hardware due to it only occurring when I'm not using the computer (physically on the computer).
It always restarts when I'm asleep or when I'm outside and gives the error "unexpected shutdown/restart". I click the more details and it says "Blue Screen".

Also, when I am using Prime95 (Small FFTs) to test stability, when I'm monitoring the computer, it's doing fine but when I leave it on overnight or go outside and let it run, the screen is frozen by the time I come back or wake up and check.

While this all happens, I use the computer quite frequency for long hours and I never experience a blue screen or freeze while I'm using it.

Thank you for reading this long post and thank you guys in advance!

If you don't overclock your CPU, do you still get the same problem?

Usually a blue screen indicates a graphics card fault. What PSU have you got? What %load is the CPU and GPU running at when you get blue screen?

Maybe someone else with an 8320 can comment on your CPU overclock

I have a COOLMAX ZX Series ZX-500 (Yes I've heard that it's a bad PSU but I bought it due to good reviews and a sale before so it was an extra part. I'm pretty sure the PSU isn't the problem here because I've been using it on my other rig and it wasn't a problem then either.)

I have no idea what % load my CPU and GPU is running when I get the blue screen because I'm not around when it happens :( 

& I'll try to see if I get the same problem on stock clocks. Thank you for replying!

Look for errors in your Windows log. Hopefully that will point you in the right direction. Blue screen can be caused by many different things including psu, ram, drivers... You need to narrow it down.

I just tested with stock clocks and it's still going on. So I'm assuming it's not an overclock problem but a hardware problem.
I'm searching for the Windows log right now and I'm not sure which one or if it even is the right place I'm searching.
I'm on C:/Windows/Logs

Thank you again!

I'm using the BlueScreenView and it's showing me my memory dump files.

The problem is (like i7Baby said) my graphics card.

It shows atikmdag.sys and dxgmms1.sys highlighted in red (which I'm assuming is the cause)

How do I fix this? Just update drivers?
Thank you!

EDIT: I just uninstalled my graphics drivers and re-installed them. I've read around that I should re-install graphics drivers because I re-flashed my BIOS revision. So giving that a try. Wish me luck!

EDIT 2: Reinstalling the graphics drivers did not work but I read else where to "overclock" my GPU. I bumped up the power from 0% to 10% in AMD OverDrive and everything is going smoothly as of right now. Thanks!
