Normally, I would say welcome to the forums, you may want to read the forum rules. But since I'm having a bad morning I'll say GET OUT.
Edit: Nevermind. Banned. Come back when you grow up.
That said, to actually *answer* the question of the poster.
A blue screen of death happens when the Windows Kernel decides it can't safely continue to run the computer. This can be caused by any piece of software that runs in kernel-land (such as device drivers, some antivirus software, or a lot of other 'priveleged' programs) screwing up and dying horribly, to bugs in Windows itself, to hardware problems (especially memory and unstable overclocks, and bad power), nasty viruses, and random glitches.
User mode programs can also indirectly cause the crash, but you'll almost always have something in kernel-land listed as the file at fault (such as nv4disp.dll, the nvidia display drivers).
Lower your OC a bit, check for new drivers (or roll back if you just installed new ones), check for viruses, and be on the lookout.
If you could tell us just which BSOD you're getting we could probably help you.
