The only things that start up are AVAST, FF, atiptaxx, & ctfmon. I'm using XP.
I tried uploading the debug log, but it's telling me I can't upload that type of file. I even tried the basic uploader. I'll post a small portion below. You can see it stalls at 13:36:34 which would coincide with the 4% I mentioned earlier. Strangely enough, this "stall" actually didn't last as long as it normally does.
