I have a Dell Inspiron 15 N5040 with 3GB of RAM (2GB of Hynix HMT325S6BFR8C-H9 and 1GB of another brand).
I used Crucial's recommendations to find out it can take up to 8GB. Money is tight, so rather than buying from Crucial I got 2 second hand 4GB sticks with specifications which I thought matched Crucial's as well as the current RAM (DDR3 1333MHZ 1.5V)
The RAM I bought second hand:
Kingston KCP313SS8/4
Kingston KTL-TP3BS/4G
I tried installing both sticks and also one stick at a time. The Window 10 boot screen appears for a second then the laptop blue screens and restarts itself and this cycle continues. When I go into the BIOS it shows 8GB of RAM, it just won't boot. When I put the original RAM back in everything is ok.
Any thoughts of what I've done wrong and could try next would be appreciated
