Looks as if I found the evil beast, turns out that it was a program called ClipCache Plus (I've used this program for at least 2 years). I found this out after getting stuck on 100% again, and after closing clipc.exe under Processes, my CPU Usage went back down to normal. I went ahead and updated the program and everything seems to back to normal. I do use this program everyday, and it makes my life easier, but for the last month it made it hard... Thanks everyone for your time you've put in to help me.

Train, I did a thorough scan on my system and found a possible trojan and one other piece of trash, I removed those...
