Hi I purchased new memory for my computer . My motherboard is msi 990 XA-GD55. Before it had g skill sniper 8gb 4x2 12800 and worked fine . The new memory is gskill ares 1600 16gb 8x2. I tried installing and got 3 beeps , tried installing old memory again and 3 beeps . So now my computer is basically out of working order and I can't figure this out . Motherboard says irs compatible with new memory and is know it works with old for works wothbold for 3 years .now it doesn' work with old or new ....

Any help greatly appreciated
