So i just tried to install this HyperX FURY Series 8GB DDR3 1600MHz RAM stick into my computer and the computer wont load up, monitor just says power saving mode. My motherboard is a MSI H61M-P31 (G3) I had a 4gb stick in before which is called Hyperam 4GB DDR3 1333MHz, when I tried to put that back in the computer still wont come back on. This is my first time trying anything like this so I am a bit lost. Any help would be appreciated.
