Blue Screen of Death

did your computer really display the image you uploaded or do you mean the regular bsod? if it's the actual image then you have a virus on your computer If it's the regular bsod, there are different reasons for that, it could be a hardware failure. Maybe your hard disk is dying on you, power is fluctuating, your computer resource (virtual ram and ram) can't handle the needs of your computer. It could also be because you're using a pirated version of windows vista or windows 7

A lot of things can cause a BSOD. Try going into safe mode then perform a disk check, if you can't get into the Windows Environment, try to use a boot tool then perform the check. You may also try to perform a system restore or just a registry restore. If all else fails, reformat the computer.

it is either hardware or saoftware

you can check on software/driver you recently install. its sometimes can cause it

A solution that worked for me is doing a check disk Start Run Type CMD Type CHKDSK /F

I think it's all because of your hardware check the memory or the hard drive! Hope that helps!
