Windows 7: BSOD randomly, often while playing Witcher 2 or Skyrim

I can understand those intentions, but they should still have the ability to unlock if you really desired the option, after all, you are paying for the product. Unfortunately the different power supply didn't fix the problem. Looks like the only option now is a new motherboard, and I feel confident that it will fix the problem since I can access the voltage in BIOS. I still appreciate all the help you provided, as it helped root out all the other potential problems first.

That is the only way to debug crashes through an online forum. Narrow things down to the likely culprit and hope it can be brought to the surface. Glad you found it helpful.

Let us know when you get the new motherboard whether it does indeed resolve all issues. Best wishes it does! I too am inclined to think it will.
