I know this was a stupid thing to do, yesterday I followed some instructions posted in this forum with someone who has the same problem (I think) as mine. I ran and installed CC Cleaner and Combo fix. I didn't realize that I shouldn't have run combo fix and I'm glad that nothing (to my knowledge) bad happened.
I re-ran them this morning and here are my latest logs, i believe the problem is fixed as the start-up screen is gone. Thank-you for getting back to me so quickly.
