Bluescreen help

[mod1fied]

Hi all,

Not sure why this happened by I just had an 0x3b BSOD whilst running a game in a window with Google Chrome in the background. After restarting I received a POST fail stating a graphics card issue. Restarting again boots Windows normally.

I've had a few problems that I think points to the motherboard recently like the POST error I stated and USB devices not working after getting the POST error.

Now I have gotten as far as debugging the minidump, but I haven't got a clue as to what I'm looking at!

Hope someone can help.
