Hi i am Chris, i am somewhat new to computers and i'm having a bit of troubling with my CPU ,which is an i5-2500k, it is running but it isn't using all four of the cores. I verified this with CPUID, advanced boot options and the task manager graphs they all say my CPU has 1 core. Is there a way that i can unlock the other 3 cores?


Look at that core speed does that mean something is wrong... it's like twice the amount of average right?
