How to troubleshoot cpu - repair guide and tips

CPU stands for central processing unit. It is an internal component of the computer. They are small and square and contain multiple metallic connectors or pins on the underside. The CPU is inserted directly into a CPU socket, pin side down, on the motherboard. Each motherboard will support only a specific type or range of CPU so you must check the motherboard manufacturer's specifications before attempting to replace or upgrade a CPU. Modern CPUs also have an attached heat sink and small fan that go directly on top of the CPU to help dissipate heat.

The speed of your desktop computer CPU or central processing unit is typically measured in gigahertz (GHz). Old computers may only have several hundred megahertz (MHz). This number indicates how fast your desktop computer can load and run programs and applications.

You can check the speed of your desktop computer CPU through "System Properties". It displays basic information about your system, including your CPU speed. To open this window, hit the Start button, right-click on the My Computer icon and select Properties in the pop-up window. Under the General tab, you can see your CPU speed as well as details about your version of Windows.
