i dont know why but suddenly i cant play .wmv files without my computer crashing. sometimes i can play one for a while but i get the weird green squares all over the video like it's the wrong codec and eventually the top half of my screen will freeze, along with the rest shortly after. random clicking around with the mouse and i get a beep from the mobo, and then it's dead...restart required. i've installed the latest media player 11, reinstalled the old one, tried codec packs, latest video card drivers etc but nothing seems to work. and i havent a clue why
