Doom 3 Choppy Screenshots

[reallyscrued]

I'm not sure if this should go here or in Tech Support, but here goes:

Everytime I use F12 to take a screenshot of Doom]|[ it chops up, its kind of hard to explain. The same strip of the screen from the very bottom is repeated over and over in stripes. I want to take just a solid shot, but I don't know what to do. I need to upload the picture, so I'll post it later. If someone knows how to fix this, pease help.

Specs:

AMD Athlon XP-M @ 12x200 1.75 vlts.
eVGA nVIDIA Geforce 6800 Vanilla, softmodded to 16x6, OC'ed to 350/785
512 Megs of Kingmaxx RAM, nothing special here
Not sure if it matters but im on a VIA KT880 chipset

Running WinXP SP2

BTW, My DOOMIII settings are as follows:

1152x854, HiQ, 2x AA, All special features including V-sync is on (shouldn't this have fixed the problem? Anyway...)

Settings in nVIDIA control panel:

AA: A-C
AF: 8x
Image Setting: High Perf
Color Profile: Unavailable
V-Sync: A-C
Force Mips: None
Conformant Texture clamp: On
Extension limit: Off
Hardware accel: Single Display Mode
Trilinear Optimization: On
Aniso mip filter optimization: On
Aniso sample optimization: On

I don't think it matters but I'm running two monitors, with the game on the primary display.
