My motherboard is an Asus PRIME B450M-A II AMD AM4.
The RAM is two 2x8GB 3600MHz CORSAIR Vengeance LPX DDR4 kits.
The computer turns on normally if I only have two of the RAM sticks inserted, and it doesn't matter which two. I was able to get it running with two of them, take them out, and replace them with the other two, and it boots up successfully again. It only seems to be when all four are inserted that there is a problem.
I can hear and see that the computer has "turned on" when this happens, but there is no display.
I can't figure out what I might be doing wrong, or if there's some reason that these parts are just not compatible in that capacity.
Any help or advice would be much appreciated.
