Go into your bios and on the Advanced tab>CPU Configuration option: Make sure that CPU Core Activation is set to auto or all cores. Then save and reboot.

If task manager still shows only 1 core then go into msconfig and on the BOOT tab click the Advanced Options button.

If the advanced options screen has a check in the box for Number of Processors then uncheck it. Save and reboot.

If this box is already unchecked then it may be that you originally installed windows with a single core processor and now need to reinstall
