Blue Screen of Deaths are usually caused by hardware failure, or certain files on your computer being missing.

If the blue screen of death flashes for just a second before switching off then it's likely a hard drive failure of some kind, check the pins are all connected from cable to hard drive, if it's a laptop, undo a screw on the back of the laptop and you should be able to find a panel where the hard drive hides, ensure the hard drive is slotted in properly. Using scan disk to detect faults is a good idea too.

If the Blue Screen of Death appears and your system halts, it's likely a software error, this can be caused by viruses deleting/modifying important windows files. If that's the case, backup the contents of your hard drive, reformat your hard drive and reinstall windows. Also if you can find the memory address on the BSoD it usually indicates the source of the error.

Myself, I have gotten a few BSoDs - All of them were caused by major lag of sorts, something like hard drive failures like Cheetah commented. It's most likely nothing to worry about, but you should look into it just in case.

I understand it, and im only 12

oo that happend to me b4

I am more concerned about black holes than the BSoD.
