Start your computer in Safe Mode to see if you get this same Blue Screen. If not try a restore at a previous date when you were not getting the Blue Screen. You can also just do the restore without trying the start in Safe Mode. What that does is let you know if software is causing the problem.

Chances are that an overclocked CPU causes such a problem.

Looking at the shot, you're probably right!

It could be any number of things, but this is certainly what I started to see when I tried to push my i7 3770K to 4.5GHz - possibly the (air) cooling wasn't quite up to it, or I hadn't set the core voltage quite right, but since I backed it off to 4.4 before Christmas it's been rock steady.

Thanks guys, you are awesome.
This is fresh windows 7 installed in new motherboard with old system, so I had the blue screen. http://www.asrock.com/mb/AMD/960GC-GS%20FX/index.asp?cat=
After reading what you wrote I had looked in the bios and saw it come with auto -overlock and the basic DDR2 667 (333MHz) don't support overlock, so I disabled it and for now the system go stable
