Problem with sprites, they are brown

i refomatted my PC because i had a windows problem and well i installed GW again and now all the char sprites are Brownish color, sometimes it goes to normal color and sometimes it doesnt. Also objects far away are also brown.

Is this normal or something?

installed new video drivers and direct X 9 ? A wipe and restore alone does not mean you are up to date by any means what so ever. Nor does it mean that windows has installed the correct drivers for anything on your system. While in many cases generic drivers work, they may not be the correct drivers for your devices. You should ensure that windows is up to date, your drivers are up to date (in particular sound and video), and make sure that you have direct x 9.0c.

LoL, I love when people say "reformatted".

Post up your computer specs and any listed updates you have done so far.
