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 :)

Have you tried holding down the power button (while battery is removed) before attempting the installation? Have you tried both of the slots?
If the sticks are not broken, I don't see why they won't work. As a last resort, try to reset the bios.

Thanks for the advice. I tried doing a power drain and inserting the sticks into each slot but no luck. I went into the setup menu on booting and ran a self test, when it reached the memory section the screen degraded into a fuzz and froze so I can only think the sticks are broken.

I think I’ll just bite the bullet and order from Crucial!
