a "seemingly" stuck pixel, but not...

[ofhellsfire]

i know this is the vidcard section, but bear with me for one moment.
last night my eye caught something that i thought was a stuck pixel, i was looking at what was supposed to be an all black screen and saw a faint blue dot. was pretty much convinced it was a stuck pixel till i took a screenshot and..... was able to zoom in on said dot. furthermore, when i drag a black image over the spot where the dot is, it leaves a trail... see pic


so its not my monitor, im now thinking a gpu problem (hence me posting it here) but to be honest i'm a bit baffled. i've tried rebooting, i've tried shutting down and letting it cool, but the problem returned the moment i entered windows (if it matters, there's no blue dot during boot, only when xp really kicks in after the welcome screen). have not yet opened case to check gpu fan. gpu drivers are current (but for the "bioshock" beta forceware release)


here are what i hope are all the relevant specs:
cpu: Intel Core 2 Duo,Boxed, E6850, Socket 775
gfx-card: XFX GeForce 8800 GTX 600M 768MB eXTreme
psu: CoolerMaster iGreen Power 600W
mobo: Gigabyte GA-P35-DS3P, S775, P35
cpu cooler: Scythe ''Infinity'' 5Heat Pipes CPU Cooler
ram: Kingston HyperX DC 2GB Kit, PC2-6400 800MHz, LL
system hdd: Western Digital Raptor 150GB
storage hdd: 4x Seagate Barracuda 7200.10 500GB
dvd-rw: NEC AD-7173S 18x12x DVD-RW
case: Antec P182
os: XP Pro SP2
nvidia driver: ForceWare Release 162.18 WHQL july 26 2007'

system is pretty much brand new, all the parts came out of the box 3 weeks ago.

if anyone has any thoughts, please let me know. thanks in advance.

Is it always in the same place on the screen?

yeah, guess i didnt mention that, but yes. always the same spot...

Has your monitor come into contact with any LSD?

Seriously though, since it comes into play only in Windows, it's gotta be something in the drivers or a GPU/memory defect. If different drivers don't do the trick, try taking the clocks down.
