Yesterday, my computer started acting sluggish. After checking the process in the Task Manager I noticed that System Idle process was hogging all of my CPU, despite having numerous apps running: photohop, firefox, xampp, a minecraft server, and eclipse. I was using the programs too. I understand that Sys Idle is running to run regardless and will run when the computer isn't doing thing but it was doing stuff. After doing a clean re-install of Windows the problem still exists. It's slowed my computer down enough to slow my computer time by about 15 minutes. I've never had this happen before. I don't know if it's a software issue or a hardware issue.
