Hey everyone. I recently built my own computer and i am very knew to this but lately i have been getting really bad lag while playing games and i cant open anything while playing or it's even worse. It constantly says 100% cpu usage and i have ran smartclose and everything. I tried going to msconfig then going to boot, advanced options, and changing the number of processors but it only says 1. I have and i5 3570k. Please help me to fix this
Open Taskbar and look the 4 tab to see the numbers of cores you have - it should read 4 .
