Hi,
I bought my PC in 2008 which has DDR2 RAM. In 2014, I replaced a new motherboard. It has two RAM slots and has 2GB RAM in one slot since 2014. I wanted to increase RAM capacity so I installed extra 2GB DDR2 RAM compatible to existing 2GB. But when I use both slots with two 2GB RAMs my won't even show bios but has power on.

But when I try to use only one RAM it works with each slot( I tried to put RAM in one slot worked, and tried with same RAM in slot2 worked but it won't work if I use two RAMs at a time in both slots). Please help me.
