Blue Screen Python

[mikcec82]

Hallo to all,

I'm using Python 2.7.3 with Windows 7 @ 64 bit
and an Intel Core i3 -2350M CPU @2.30GHz 2.3GHz.

Sometimes, when I'm programming in Python on my screen compare this blue screen:

Can you help on what is the issue, and how I can solve it?

If you need more info I'm available.

Thank you so much,
Michele
