BSOD on hourly basis Locale ID 1033, BCCode 3b

I notice that you have windows 7 Enterprise edition, did this PC come form your work/had windows installed by the company you work for? If it was I would contact your IT department before actually doing anything to the PC. If it was not installed by your work then the install is likely counterfeit, as Enterprise edition is only sold in bulk not in single copies.

I will need to check on hat please hold tight, I will ask one of our licensing experts about this and see what he has to say. in the meant time try running some virus scans using Malwarebytes and Tdsskiller to make sure there isn't an infection on your PC

unfortunately you may be right about the hardware, but before you go spending money (unless you want to) lets try a few things

So you are aware it appears that your graphics card driver is at fault here:

Code:

fffff880`08ef8bc8  fffff880`05b0ece4Unable to load image \SystemRoot\system32\DRIVERS\atikmdag.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for atikmdag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys
 atikmdag+0x98ce4

Driver Reference Table - atikmdag.sys

The driver its self is up to date:

Code:

start             end                 module name
fffff880`05a76000 fffff880`065e9000   atikmdag T (no symbols)           
    Loaded symbol image file: atikmdag.sys
    Image path: \SystemRoot\system32\DRIVERS\atikmdag.sys
    Image name: atikmdag.sys
    Timestamp:        Thu Mar 28 22:27:04 2013 (5154FBF8)

    Translations:     0000.04b0 0000.04e4 0409.04b0 0409.04e4

which could point to two possible things, a bad driver, or hardware problems. So lets start with the simpler of the two to diagnose, which is the driver, to do this please do the following:

Open the start menu and right click on computer

From the drop down menu select manage (this my bring up a UAC prompt accept it if it does)

In the computer management window expand the system tools and double click on device manager

Once in the device manager window expand the display adapters

Right click the item named after your video card and select properties

In the properties window select the driver tab

In the driver tab select roll back driver, you may need to reboot once this completes.

If this does not work and you still have BSOD problems then please run the following hardware tests:

Furmark to stress test your GPU:

FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

FurMark Setup:
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature" (BurnIn test in newer versions).
Click "Go" to start the test
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
- Click "Quit" to exit

Video memory stress test:

Allow this to run for at least 8 passes

Technically, Enterprise Edition Licenses belong only to the company - and cease to be valid if the company ceases to exist for whatever reason, or ceases to update its volume licensing.
That said, it doesn't usually cause problems until either a reinstall is required, or validation fails.
For what version and edition of Windows is the machine licensed, according to the COA sticker on the case?
