  •  Unit with one RAM stick 

Move the RAM stick to another RAM slot on your motherboard.

If the error occurred only on a specific RAM slot, the motherboard RAM slot is defective. If your motherboard still has a warranty, please claim it. If the warranty is null, please use working RAM slot.

If the error follows the RAM using other RAM slots, the RAM is defective. If your RAM still has a warranty, please claim it. If the warranty is null, please buy a new one.

  • Unit with multiple RAM stick 

If you have installed a new RAM stick and you encountered the error, it might be the source of the error.

If you have a multiple RAM, try to determine which one is causing the problem by using the RAM one by one and using only one motherboard RAM slot. If one of the RAM enables you to access Windows Desktop please create a bootable Memtest86 or use Windows Memory Diagnostic to test your RAM. If the RAM passes the test please test another one. If one of the RAM encounters an error while the other pass, please claim warranty. If the warranty is null, please buy a new one or use the working RAM only.

If all of them fail using a same motherboard RAM slot, it is possible that the RAM slot is defective. If all of them pass the using Memtest86 or Windows Memory Diagnostic by using the same RAM slot, it is possible that one of the RAM slots is defective. Use the other RAM slot to confirm.

If the error persists, please install new Windows.
