Question Random Bsod memory problem

[RSMafia]

Hello. So this is a bit complicated. I get a lot of random Bsods on my pc resulting in a restart. They are completely random and it doesnt really matter what im doing on the pc. I have two 4 gb sticks of ram on a Asrock h61-m dgs motherboard ( only two slots of ram). When im using only one stick of ram it seems to work just fine but sometimes i get 4 beeps when trying to boot the pc and no display . This happens with both of them and it doesnt matter in which slot they are. Its just like sometimes they work perfectly and sometimes they don`t work at all. Some of the bsod are Memory management , irql not less or equal attempted to write to readonly memory and many more.
How should i solve this and what is the problem? The ram? The motherboard? Something else? I ran memtest86 and it said no errors... :|
