As previously mentioned, BSoD errors are commonly caused by faulty RAM, so it’s always a good idea to test if your RAM is working properly.

To do so, you can remove one or more RAM modules and check if your PC works well without it.

You might have to test all RAM modules one by one before you find the one that is causing this error.

In addition to removing RAM modules, you can also use tools such as MemTest86+ to test your RAM.

Create a bootable USB or CD with MemTest, and boot your PC from that USB flash drive or CD. Start MemTest and let it test your RAM for a couple of hours.

To find the faulty module, you might have to test one memory module at a time before you find the faulty one.

In addition to your RAM, any other hardware component can cause this error, so be sure to check your motherboard and hard drive as well.

It’s also worth mentioning that any recently installed hardware that is not fully compatible with your PC can cause this error, so make sure to remove or replace it and test if your PC runs without it.
