My PC is restarting randomly after I installed +8GB RAM

Specs:

Motherboard: Biostar a320mh.

I decided to add +8GB of RAM in my computer. I bought the new memory four days ago and since then sometimes my computer randomly restart.

I don't play video games and it restarts when I'm doing usual things like watching videos etc..

It only happened 3 times but I wonder why is that happening?

 

I don't speak English properly and if there are any information that wasn't clear let me know.

The memory might be faulty... try something out like Memtest86 and see if it has any errors
