So, if your hardware system is up to the mark and if you think that there is no such issue with its compatibility, then possibly there is a fault in RAM memory card chip. You can consider some of the following points mentioned below:

1. First of all, RAM memory cards are made with a perfection and quality by the tech companies. So, if you have purchased RAM from a low-level company, then there is a very high probability that RAM is a defective. Always purchase computer peripherals from named brands of this field like Samsung, Kingston, Corsair, etc.
2. There is also a chance that your PC is loaded with outdated processing drivers and chipsets. So, kindly upgrade them to their latest version to use new RAM chip in your PC.
3. There is also a probability that the CPU coolers of your PC is not working properly which results in the overheating. Please check the CPU coolers and if they are not working properly.
4. Incompatibility of PC’s hardware with the RAM chip may also raise this issue. Because users just purchase RAM of higher memory without analyzing the hardware compatibility of their PC with it, that’s why this issue rises.
5. Another very common issue is the lack of knowledge among the users. Sometimes, users insert the RAM chip in the wrong slot which results in this issue. Make sure to insert the RAM chip inside the slot which is reserved for it.
