I played a video once, and the same thing happened. I added another stick of memory and there was no further freeze. This is only my experience!
Recently reloaded Windows XP Pro (after a bad SP2 update...) before this reload had no problem with with Windows Media Player (WMP).
Since the install and all updates from windows update, my WMP 9 started locking up after a few min's of play. It does not matter if it's audio or video, and it locks the entire computer! No Ctrl-Alt-Delete, just a frozen screen!
I upgraded to WMP 10 but still same problem.
Anyone have any idea's as to what is broken?
