Can someone tell me why my CPU usage is at 100% when i don't have any programs open but the ones that are on at startup
you probably have spyware, trojans, virus's on your pc. This is a common problem for proceesor load at 100 percent. I would reccomend getting avg antivirus software, the free version and running it to see if it find something. the link http://free.grisoft.com/doc/1 also run this from microsoft http://www.microsoft.com/security/malwareremove/default.mspx
