I just bought some RAM to add into my computer to go from 8 to 16gb and my PC basically starts up a few seconds and shuts down. It does this continuously until I switch it off. It does not even reach POST. I'm thinking it's a PSU problem, as it isn't a very good PSU. The PC boots up with 2 sticks of either old or new RAM (tried both), but not with 3-4. Anyways, here's some specs:
Motherboard: GA-Z77-D3H with latest BIOS.
CPU: i5-3570k with Coolermaster cooler.
GPU: GTX 670
RAM: G.SKILL Areas F3-1600C9D-8GAB. Have 2x4GB and was adding 2x4GB.
PSU: Rosewill RG630-S12 630 Watt
1 SSD and 2 HDD
