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.

I would check my bios and make sure the cores are turned on there. Also since you did a format have you made sure you have the proper drivers installed. I don't have a copy of your setup manual and if you don't please contact the manufacture for one.

You may also need a patch for the game to be able to utilize the extra processors, or try your game preferences to active them.


rj713 is right. The two things to check are the BIOS and the drivers. If they're showing up in the Task Manager, I doubt there's anything wrong with the cores themselves. Even if there were, the likelihood of 3 of them going out at once is pretty slim.

Is an easy fix this one.

press the start button, type msconfig.

under the boot tab select advanced options.

you will see a tab with number of processors, click on and your 4 core option will be there.

click apply and finish and reboot.
