I have an Alienware Aurora R14.

It currently has Kingston Fury 8gb x2.

A friend sent me some RAM to try (G.Skill Ripjaws 8gb x4) but it had made the power button flash upon reconnecting the power cord (Amber x3, White x1) which online said is a CMOS issue.

I've since swapped them back and reset the CMOS and it's currently working on the original RAM, I've just been considering turning on XMP in the OC part of BIOS to re-try the other ones.
