I am running Windows 2000 PRO with an AMD Thunderbird 900 in a Shuttle AI61 motherboard with 256MB of SDRAM. Nvidia TNT2 Pro video card with 32MB. now the problem....everytime I try to view video or listen to music using Windows Media Player, my system totally freezes and I have to reboot. I can't seem to do anything to help the situation. Anybody else experienced this??
