The CPU (Central Processing Unit) of your PC is the part of your PC dedicated to the actual computation function that computers were meant for. It issues instructions and process data and is responsible for dishing out instructions about how the data should flow. As the brain of a human, a computer is completely useless without a CPU help.

Because of the skill and expertise that most manufacturers apply when building their computers’ CPUs, it is quite rare for a CPU to just die. In fact, some hardware engineers admit that throughout their experience at repairing the different parts of a computer, then seldom encounter dead. This goes a long way to show that it is a scarce thing.

What is Responsible for the death of CPUs?

What isn’t rare, though, are the reasons chips typically die. One of the reasons for the death of CPUs is that a user is getting over-enthusiastic with his overclocking efforts and pumping too many volts into the chip. If the CPU over-stresses the components connected to it, then damage can spread beyond the CPU itself.

Also, another primary reason for the death of CPUs is due to improper thermal compound application. In fact, this thermal damage can end up killing the motherboard too.

How to Fix Dead a CPU

Straighten out the Bent Pins

There is a very little chance that your CPU will come back to alive if you straighten out ALL the bent pins. You may have missed some bent pins. If, after switching your PC on, there is some error message on your computer screen about a dysfunctional CPS, this option may likely get the problem fixed.

Install New Parts

If your CPU has been irredeemably impaired, you can install a fast, fresh CPU to your PC. This is especially important if the first option about the restoration of a dead CPU isn’t feasible, you may want to install new parts for it. If you set out to do this, be sure that do it carefully and slowly. Also, don’t forget to get some drivers installed. Anything contrary can yield undesirable results.

Can a Dead CPU Affect your PC’s Motherboard?

In a multi-CPU system, the death of one CPU may not kill the whole motherboard. In laptop and tablet systems, the CPU is often soldered directly onto the motherboard and not fitted in a socket. If a CPU dies, then replacing the whole motherboard may be the cheapest solution. On desktop type systems, the CPU is frequently socketed and can be swapped quite easily.

If there is only one CPU in a system and dies, it can sometimes be complicated without specialized equipment to locate the fault. Complete replacement can be the simplest way forward.

If you use a dead CPU in a motherboard of its slot, it may harm the motherboard for creating slow short circuits that do not appear instantly, but with time, they do occur when power is throughout the motherboard from an SMPS for a long time.
