Happened while playing Skyrim. Possible causes are Memory problems... Graphics card memory problems... BIOS... Corrupted hard disk file system... Corrupted System Files... Missing Windows Updates... Drivers...
Thanks to Dave76 for help understanding possible causes.



Run through the following steps:

• If you are overclocking any hardware, please stop.
  
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
  If you swap any memory components, follow these steps for ESD safety:
  
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
  
  Once these steps have been followed, it is safe to remove and replace components within your computer.
  
  
  
• An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
  
  a. Backup your system and user files
  b. Create a system restore point
  c. If you do not have a Windows 7 DVD, Create a system repair disc
  d. Run Driver Verifier
  
  If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.
  
  Thanks to zigzag3143 for contributing to the Verifier steps.
  If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.
  The idea with Verifier is to cause the system to crash, so do the things you normally do that cause crashes. After you have a few crashes, upload the crash reports for us to take a look and try to find patterns.

So it could be faulty HDD? or Faulty Ram?

Nothing points to a hard drive. That is just one of the possibilities of that type of crash. The main two likely culprits of the memory corruption being blamed as the probable cause are faulty RAM or a driver that is accessing RAM in a way it should not. That is why the two steps were outlined in my post for you to follow.

Disabling any overclocking is requested to remove that as a possible cause of instability.

Yeah I don't overclock at all, I'll be really sad if it's my ram, I bought really nice Corsair ram

I'll give memtest a go and suss it out, if its a driver accessing it in a way it should not be whats the best way to determine which driver?

The steps to run Verifier will root out which driver. By turning Verifier for all non-Microsoft drivers, your system will be forced into a state that causes driver conflicts to become apparent through blue screen crashes. That way, any crash reports generated will point to driver conflicts, and we can analyze them to determine which drivers are conflicting.

Yeah i have that on atm for all non windows related drivers. so next BSOD hopefully can narrow it down i'll run memtest and get back to you.

thanks so much for your help.

Might also want to check with Skyrim's developers as it appears there are a lot of issues with it in win 7

Any luck with Verifier? Did you have any more crashes to analyze?
