PC wont take screenshots on anygame...

[Seriously Deadly]

I have had this new setup for about a month, with vista, and some new hardware.
I have three games installed:
Serious Sam FE
Serious Sam SE
Call of Duty 4

on all three games when i take screenshots, they dont save anywhere.
Even the PrtScn doesnt take pictures anymore (it did untill SS:FE was installed), it takes pictures of the main game menu, on CoD, and just the bomb logo from when the game loads on SS. Theres no screenshot folders either, in all the games folders. The wierd thing is in SS, when i press f11 it even says Screenshots/Hole_screenshot001, or what ever it says in the console.
I have tryed reinstalling SS:SE and FE, with no changes, and i really dont want to reinstall CoD4.

Any help would be apreciated, thanks.

I never use the screenshot feature that is built into games, I use a 3rd party program to do mine.

Google something like "free screenshot program vista" and you might find something.

I'm going to move this to the Software section

This one claims to work with Vista.
