graphics problem under xp .. display colours changes and sound is not that clear

i have an iMac, 2.8 24 ATI NX2600

under windows, i sometimes face this problem where the screen colours are awful, maybe a screenshot is better to describe it



the billiards table is supposed to be fully green and no gradients. u can also see that the task bar and firefox title bars are affected.
and i am sure it is not the games that make it like that as i dont do games, except for that flash game.

the sound coming from the butin speakers and the headsets is awful and contains noise

i this happened when i was the boot camp 1.4 drivers and i updated it with the ones that came wtih leopard but still the same.

the sound in always awful while display only sometimes gets weired.
i am positng this in different locations as it is related to different forums.

hope someone knows the problem and of course a solution.
thanks

 

obviously none responded because none understood what the problem was.

anyway, i just discovered that u are seeing a nice and sharp picture instead of what i saw when i took the screenshot. this means the graphics card processes the colours well but the dispaly isnt displaying them well.
which means the problem is in my imac display which displays the colours blurred and it is like water spilled on a painting.

maybe if u go to photoshop and add intense Gaussian blur to the picture above it will be like the one i had.

it sometimes makes shadows.

after this mess, i wont expect much from this thread.
