I recently bought a corsair 8gb ddr3 1600mhz ram. The problem is since then my computer keeps turning off and on again when i try it on, but my 2gb ddr 665mhz ram is still working fine. I think it's my msi 2a9c motherboard that's the problem. Could somebody help me please i`m only 15 so buying that ram cost me a lot of my allowance, Please help.
