dead pixels only with Media player?

[P A U L]

i noticed something last night when i tried to watch a video on my PC...

black dots appear on the screen, when i move the media player around, the block dots stay still, but they leave trails of black lines whenever i move the media player, when i let go of the media player. the lines disappear. but the dots remain..

these dots are about 1 pixel... are next to each other by pairs. vertically.

and are lined up seperately from the other pairs, going diagnolly, about 2 inches apart. kind of like... stairs

i noticed, if i load a video on MplayerA, and load another video on MplayerB, those dots dont appear again on MplayerB.

i have tried loading different kinds of files, even when i tried to load a video on Winamps media player, these "dead pixels" show up.. i uninstalled all the codecs in my PC, and deleted all the residue codec files that i could find, and it still does this.

what can i do!!!!!!!!!!!!!!!!!!!

anyone ever hear of such problems? or experience yourself?


system:
Windows XP SP1
P4 3.0GHz HT(disabled)
ATI X800XL
1GB DDR2 RAM
