Over the past few weeks, I have been attempting to "tweak" my computer to allow for better gaming. I have an older Dell with a P4 and 1 gig or RAM running Windows XP HE. I have been tweaking via msconfig and also services. Now, I have done something that whenever I try to play a video through Windows Media Player, the video will not play, it seems to stick with the message "opening media". I then shut down WMP, but when I do, my screen refresh rate sits at a crawl. I then open Task Manager and find that explorer.exe is using 99% of my CPU. As soon as I end wmplayer.exe, the CPU usage goes back to 2% and all is good again. Does anyone have any ideas what I may have done to get this? Thanks in advance.
