Intel quad Q9000 processor only using 1 core on G72GXA1 Asus Laptop?
When i bought this laptop all of the cores where working fine, but after a virus and a format only 1 of my cores is working. I have windows 7 64bit and when i open taskmanager and go to performance it shows all 4 cores, but when i try to play a game only 1 of these cores is being used. I noticed this because my games began to inconspicuously lag, and that is when i say that 1 core was maxing out and the rest were not even doing anything. Could someone please tell me how to fix this, and try to stay away from the answer, "Buy a new processor" unless necesarry. Thank you in advance.
