Try using different RAM modules or a spare graphics card to isolate the problem. If possible, test your components on another compatible system to determine if they are the cause.

8. Understand LED lights

Many computers have LED lights that indicate the status of the computer. If the LED lights are not lit up, then there may be a problem with the computer. The meaning of the LED lights will vary depending on the computer model.
