How Do I Know If I Need a New Processor?

CPU (Central Processing Unit) processors may develop problems from too much heat or power irregularities. If your computer is behaving erratically or appears dormant when you power it on, it's possible that the processor needs replacing. The easiest way to find out if you need a new processor is by testing it in another computer with an identical processor. Before working inside your computer, wear an anti-ESD wrist strap to prevent an electrostatic discharge.

Things You'll Need

• CPU (central processing unit) processor
• Anti-ESD (electrostatic discharge) wrist strap
• Phillips screwdriver

Instructions

1. Unplug the power cords that are connected to an electrical outlet and your computer. Find a workspace that is uncarpeted and free of static electricity to avoid damaging the CPU.

2. Open your computer case. Use a Phillips screwdriver to untighten and remove any screws from the chassis.

3. Disconnect the small power cables that are attached to the cooling fan and leading to the motherboard's power supply.

4. Remove the cooling fan that's located on top of the CPU. Loosen and remove the screws that are attached to the fan unit.

5. Lift the fan off the heatsink, then remove the heatsink from the CPU. You may need to use the screwdriver again to remove any screws that are holding the heatsink in place.

6. Pull the ZIF socket lever up until it is perpendicular to your motherboard. The CPU will pop up and out of the socket. Most motherboard models have a ZIF (Zero Insertion Force) socket lever to secure the CPU onto the motherboard. If you have an older motherboard, you may not be able to remove the CPU.

Tips & Warnings

• Once you have ruled out most common problems, such as software or hardware conflicts, add-in cards and loose or incorrect connections, then purchase a new processor for your computer. Make sure your motherboard is able to support the type of processor that you want to buy.

• Depending on the make and model of your motherboard, you may need to configure the board for a new processor and adjust some settings in the BIOS (Basic Input Output System). Refer to the documentation that came with your computer about your motherboard. If you do not have this information available, browse the Internet and visit the manufacturer's website. More often the manufacturer will provide additional information about the motherboard and the type processor that it can support.
