I finally got a BSoD on my Vista when I'm using VirtualBox to emulate OpenSolaris and Linux.

VirtualBox costs 512MB per window

BTW: How to take screenshots of BSoD or login screen?

Well, since some buttons go out when BSoD happens I would try using a camera.

You can take a screenshot of any virtual computer, such as those in VirtualBox or, like me, Microsoft Virtual PC. But if the main system goes out, I recommend using blueheat127's option of using a camera. You might want to make it quick; some blue screens automatically dump the RAM then reset the machine.

Yes, my main system got BSoD
but how did people on Wikipedia took BSoD screenshot in full quality

They are likely taken through a virtual machine. All of my Mac OS 9 and prior errors (except one) were taken through a virtual machine and well as several of the Windows 3.1, 98, and 2000 ones. (Oddly, two of the 3.1 errors was taken on a real Windows 3.1 system. ) All of the 95 images were from a real 95 machine, as well as all the XP, Vista, and Mac OS X ones.

Today is a bad day. I just got a BSoD, AND a PSoD on my DS.

yeah you overwork vista and it likes to BSoD, not a pretty thing
