Frequent BSODs after changing Graphics Card

I just got it back and they've exchanged RAM. It's working just fine now and I hope it'll be so in the future, but there is a question: why RAM failed when I plugged new video card in? And how am I supposed to upgrade the card without such issues?

EDIT: The new card (Radeon 6770) is still at repairs.

It is likely the RAM was bad before the video card was plugged in, but due to the video RAM increase or video RAM speed increase, there was more data being swapped through your RAM and the previously unknown faults caused crashes.

Well, I'd like to say that everything's fine and working properly, but I can't. BSODs are still there. Latest minidumps attatched.

I think maybe there's something wrong with the slots, not the RAM itself.

EDIT: What about the PSU? Is it possible that 420W Tracer works better than 500W Chieftec?

Unless you have a faulty motherboard, I would not suspect the RAM slots. Was this latest crash without the new graphics card in?

The latest crash indicates memory_corruption. Since the RAM has been replaced, I suspect a driver issue. I do see your Atheros LAN driver is out of date. Please update it from MSI Global ? Mainboard - 760GM-P33


I also still see nVidia software installed. Is this intentional? Are you now running with your old nVidia card again?

Check your drivers:

• 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. In Windows 7:

  • Click the Start Menu
  • Type verifier in Search programs and files (do not hit enter)
  • Right click verifier and click Run as administrator
  • Put a tick in Create custom settings (for code developers) and click next
  • Put a tick in Select individual settings from a full list and click next
  • Set up the individual settings as in the image and click next

  • Put a tick in Select driver names from a list
  • Put a tick next to all non-Microsoft drivers.
  • Click Finish.
  • Restart your computer.

  
  
  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.
  
  When you are ready to disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
  verifier /reset
  -> Restart your computer.

OK, I think that will be enough. Verifier is reseted.

Looking more and more like hardware... Let's check if the RAM is compatible with your motherboard and processor:

Download and install CPU-Z and Upload screenshots of the CPU, Mainboard, Memory, and SPD tabs. In the SPD tab, upload an image of each slot.

OK, here are requsted screenshots.

AMD processors' memory controllers have a hard time handling 800 MHz RAM without BIOS setting changes. It appears your RAM is overclocked, anyway, so please clock it down to 666 MHz. The first four timings should still be 9-9-9-24. See if that provides more stability.
