Started having problems a few days ago. PC took longer than usual to boot. Browser (FIrefox intially and now IE) will work fine for about 20 mins, then begin to load back to the previous screen and not allow anything else to get through. You can see it trying to move to something else, but then it will "snap back." At that point, other applications are unable to run either. Ran the 8 steps last night...here are the logs. Thank you in advance.
