"Ahh yes, and did it tell you that the drivers weren't signed? Just because it says "Designed for Windows XP" doesn't mean it's signed":Winged elf

"For example, I naturally suspected my hibernation troubles above were video-related, but I was using drivers supplied by Microsoft itself, with all proper certifications and signings."
So wise but clearly unable to read an article properly

Let me point out a certain phrase which should explain everything:

I then visited my video-card vendor's site (Nvidia) and downloaded its "designed for Windows XP" drivers

Now figuratively, Nvidia's drivers are not supplied by Microsoft, and with the exception of the Detonator 6.50, 12.41, and possibly the 21.81 drivers, they are not signed drivers. If it comes up with a warning upon driver update that the drivers are unsigned, and he glossed over it and installed them anyways, then that's his problem.
