Caught by the torrent of life

I would have not known about this issue that seems to affect quite a lot of the Windows 7 and Vista users, had I not encountered it myself the other days. If BSOD, the Blue Screen of Death is more widely known and causes are being addressed (more or less), the KSOD, or blacK Screen of Death is less encountered and causes I would say are still to be identified. Affected Operating Systems are, from what I've come across the internet, Windows 7 and Windows Vista.
