Computer Problems

My computer has taken a spiral down. Its getting worse each day and I don't want to lose it all together. I don't know what all to do to fix it. My bitdefender is sadly not finding any problems, but I know they're there. I have HiJackThis and here is a copy of the log i retrieved. Any help would be greatly appreciated.
