Introduction: CPU Diagnostics
The CPU is the central processing unit of the computer. It computes different processes as it says in the name and it also communicates with other parts. It takes in input and other processes then does the main computing. After this it sends 1s and 0s to the other parts to tell them what to do.
Step 1: CPU Problems and Diagnostics
Common problems with the CPU that affect computer functions include:
- Over heating
- Thermal paste issues
- Bent pins
- Broken CPU fan
Diagnostics: the common symptoms
- No image when turning on the computer
- Boots up but shutdowns randomly
- Will boot up but tell you "no CPU fan detected"
- Replacing thermal paste
- If pins are bent then replace CPU
- If fan does not spin replace fan
Step 2: How to Get to the CPU
If you believe that your CPU is causing you issues. First you will have to get to the CPU.
- First you will want to unplug your CPU fan
- Next remove your CPU cooler
- Lift the leaver holding down the CPU
- Carefully remove the CPU from the holder
- Be careful not to bend any pins\
- If you notice a bent pin that is your issue
Step 3: Thermal Paste Applacation
- First you will want to remove the current thermal paste.
- Do this with a micro fiber cloth
- Apply rubbing alcohol to it
- Then rub the paste off
- Place the CPU back into the socket
- Make sure you align the special corner with the marked corner on the socket
- Then push the arm down
- Next put a small dot on the CPU
- Then place back down the CPU cooler
- Make sure you plug in the CPU fan
We have a be nice policy.
