Theres no welcome screen, not even the BIOS.
The only thing youre seeing is a black screen.
Youre probably frustrated and wondering who the culprit is, and how it happened.
Well, dont worry.
The solution to your problem may lie in the CPU checking process, called POST.
And this article will help you with information and the ways to resolve it.
So, lets begin.
What is POST and How is it Work?
Its a basic process that verifies the viability of the parts to initiate the PC properly.
If the POST process completes successfully, it goes to the operating system and boots up the computer.
Various components are responsible for the no POST process.
The following passage will describe if the processor is accountable for the no POST condition.
Can a Bad CPU Cause No POST?
Yes, a bad or faulty processor can cause no POST to the computer.
Without a functional CPU, the BIOS fails to complete the POST activity and is unable to display anything.
As a result, the computer doesnt boot up and shows error messages with beep noise or LED indicators.
Its a vital component, and damage, burning, or fault can lead to the no-display issue.
Themotherboard doesnt POST without a CPU.
Whenever it detects a problem, the system board gives a signal with a beeping noise.
There are different beep codes, which indicate the possible error with a component.
Ive provided the POST beep codes regarding the bad CPU below.
Why Does a Bad CPU Cause a PC Not to POST?
Also, the Power-On-Self-Test process may fail due to excessive CPU temperature or processor burning issues.
In most cases, a bad CPU refers to external damage to the processor.
It leads to theCPU failing or deadand causes a black screen.
The following passage will explain the reasons behind the bad CPU which is hampering the POST process.
Usually, the processor fits and installs normally on the CPU socket with the guidance of cutouts.
The processor is made with a chip and is very fragile.
Any internal or external damage to the CPU can make the processor faulty.
If you harm the processor during the installation, the PC may not turn on.
Also, abent CPU pin is badfor the computer and can lead to the no POST issue.
Everyprocessor has a temperature limitfor each condition.
Usually, a CPU can endure up to 90-95 C for a while.
Beyond that, the temperature is bad for your processor and has a higher possibility of burning the CPU.
Also, overheating issues can significantly decrease the CPU lifespan and break your CPU quickly.
Read the following procedures to prevent the no POST issue because of a bad CPU.
Here are the ways to overcome the no POST issue due to a bad processor:
1.
Check out all the cutouts and triangles toinstall the CPU correctly.
ensure to pull down the socket lever properly and fit the processor well to the socket.
Improve the Cooling System
A sufficient cooling facility is a must to keep the CPU temperature down.
Otherwise, a hot processor can give you a warning and hinder you from opening the computer.
