|1. your questions have absolutely nothing to do with CPUs or overclocking.|
2. we have to ask you for specs?? No. You're supposed to include them in your post.
3. your system is a low end/budget machine. The specs are horrible...low end CPU, crappy SiS based board with weak graphics, not enough RAM, etc. You obviously didn't just buy it from BestBuy because it's almost 4 yrs old.
If you wanna get rid of the packaged software, go to Control Panel > Add or Remove Programs & uninstall them one at a time.
