If you happen to see blue screen on Windows, it's most likely a hardware or driver problem. It is not Windows 9x days when a user program could take down whole OS with ease.
Ya got bad hardware friend, the only time I've seen a BSOD in the last few years was when something on my work laptop went bad and it had to be replaced. I haven't seen a BSOD on my personal machine since my last DIMM failure.
I assume that like 9/10 comments in here won't be serious. Why are you all taking it so seriously? Yes, windows is very good and it's rare to have a blue screen now, compared to the good old Windows XP days...
