(SOLVED) Why is my PC Not Booting After Changing RAM Speed?

Why is my computer not booting after changing RAM speed?

The main reason why a computer is not booting after changing RAM speed is because of the Incompatible RAM with the motherboard or the RAM sticks not seated properly in their slots.


Here is a roundup of the factors that cause your computer not to boot even after a significant change in RAM speed:

  • Wrong RAM slots
  • Issues related to CMOS battery
  • RAM sticks are not seated properly
  • RAM unable to adapt to the working motherboard
  • Installing bad RAM sticks
  • RAM adapting to the motherboard


Wrong RAM slots

Computers with four RAM slots will give you slight trouble when installing RAM. It is because there are certain combinations that you have to follow. The failure to follow these combinations will result in a few problems with your computer’s working.

For example, if there are four slots labeled as 1, 2, 3, and 4, you will have to insert RAM sticks in 1 and 2. If you insert it in 3 or 4, the computer will not work properly.


Issues related to CMOS battery

The CMOS battery is the main engine of your computer system. Any problems in the battery will cause serious disruptions in the otherwise smooth working of your computer.


RAM sticks are not seated properly

The computer’s hardware should be installed properly and with attention to detail. If RAM sticks are not laid down properly, they won’t work.

As a result, the computer will keep turning on and off. You will have to ensure that the sticks fit perfectly into their slots to avoid this problem.


RAM unable to adapt to the motherboard

Many computer owners think that all RAMs are compatible with all motherboards. This isn’t the case.

If you recently installed RAM and found out that the computer is still showing problems, you should consider determining if it is compatible with your motherboard.


Installing bad RAM sticks

Bad RAM sticks also cause many problems for your computers and frequently force them to turn off.

If you have installed bad RAM sticks into your computer and it keeps turning off, you shouldsee if there are any bad sticks.


RAM adapting to the motherboard

After installing new RAM sticks, the PC turns off as part of the installation process. This step lets the newly installed RAMs effectively adapt the motherboard’s working.
