I have had Windows XP, media player 9, and an old GeForce video card for\nquite some time with no problems. I just got a new ATI X800 card, and now\nwhen I use media player to play an mpeg it locks up my whole computer. I\nhave to manually hit the reset button. It will play about 2 seconds of the\nmpeg, then freeze. The computer is actually operable UNTIL I attempt to\nclose media player. Then it's a total lockup, every single time. Quicktime\nand realplayer work fine (and so do games, etc), so I know it's not the video\ncard. I've got the latest drivers for the card. I also installed media\nplayer 10 but that had no affect. Any suggestions? I'm almost to the point\nof never using media player again. I wish I could uninstall it.
