Stupid Computer

I hate my stupid computer! Just yesterday it was working fine now whenever I watch a video or play a game it'll pause for a moment then keep going! And it's not only once it happens every like 30 seconds! It's so annoying! I think I know whats doing it, the only thing I installed before I noticed the problem was Halo: Combat Evolved PC Trial Edition. This game might be the problem. So I might need to uninstall it. Unfortunately I like that game :( fortunately its only a demo so I can handle it. In conclusion I'm going to uninstall it. If this doesn't work will people who know what the problem is please leave a comment or contact me via e-mail. Wow that was a mouth full. See Ya!
