O.K. So I've got a little bit older of a computer. 2.6 ghz p4 1 gig of ram 160 gig hard drive. It's a HP pavilion a520n. The problem I'm occuring is that when I open task manager I have MANY proccesses running under the user name SYSTEM, and my computer has been getting gradually slower, and slower. It's not nearly at the running speed it used to be. So what I'm wondering is will a hard drive wipe help speed it up to the way it was when i bought it? Any suggestions on programs/ways to do this? Any advice is appreciated TY and have a good day.
