Vista: No sound and all media files playin too fast

Ok, so I installed Windows Vista SP2 after having some malware problems.. Thinking that this would give me extra security.
I must admit, that I had some difficulties. I also had Deamon Tools installed when installing SP2, and now i read that that could be dangeorus. So now Ive uninstalled it.
But I have these video files-problems: All video-files (even youtube!) play too fast, and there is no sound. So, Id really like to know: Would you recommend me to uninstall SP2 and then trying to reinstall it?
Or could that be dangerous?
