My comp is a compaq XP3200, gig ram, Windows XP Professional. Everytime I open up a video file or if I happen to go to a website that has a video that starts playing as soon as the page pops, my computer freezes up. It won't play the video and if I let my comp sit for about 1-2minutes sometimes I can cancel the video then the my comp slowly starts working as quickly as before. I have a 6600GT and installed the latest video drivers fromn Nvidia using drivercleaner, but that didn't help. I don't recall an exact instance that made this start occuring. I'm thinking of reinstalling windows if I can find my disk, but I'd rather not do that if it's something minor that needs to be addressed. Also, I use AVG free edition and it's fully updated and I scanned my comp twice and it didn't detect anything. Any suggestions? thanks
