In personal computers or laptops with dual-core processors running Windows XP, two cores are most often used by default, but some of the programs require one of them to be disabled for correct operation.
Instructions
Step 1
Make sure the second core of your processor is disabled. To do this, open the Task Manager by simultaneously pressing the Ctrl + Alt + Delete or Shift + Ctrl + Esc buttons.
Step 2
Select the "Performance" tab in the window that appears. Look at how many windows the "CPU load" (processor load) part is divided into. If you have two processor loading windows in front of you, both cores are functioning at the proper level. If there is only one window, then only one processor core is enabled. In the second case, you will have to perform the following steps to enable the second core.
Step 3
Download the Windows XP Optimizer and install it on your computer. It will allow you to properly configure the processor. After installing the program, go to the "hardware control" item on your computer and turn on the work of the second processor core.
Step 4
Reboot the computer or laptop, and it is necessary to reboot even if the optimization program does not require it. After changing the parameters, do not forget to save the changes by clicking on the appropriate button - "OK".
Step 5
Check the operation of the processor and, accordingly, its cores. To do this, turn on your computer. Run any program or game with the system requirements for a dual-core processor.
Step 6
Start the task manager (Ctrl + Alt + Delete or Shift + Ctrl + Esc), go to the "Performance" tab. Look at the load on both elements of the processor. If you have two windows, then all actions have been performed correctly and the second core of the system is turned on. At the same time, remember that the load on each of the cores can be different, since it is not always distributed evenly.
Step 7
You can turn on the second processor core in a slightly different way. Install the rollback driver for the motherboard. Reinstall the software, it is best to use updated versions of the software for this. Restart your computer, check the operation of both kernels in the device manager using the above method.
