I am using Lenovo B470 old one for a while and decided to upgrade ram 2GB to 4GB . I just bought silicon power 2GB DDR3 - 1600 L according to crucial and local store .
When I added both ram sticks and turned on my laptop , laptop tried to boot and light on and sound appear "click" (only one click,not a continuous one,I think from drive) and then turned off, 3-4 s later, light on - click - shut down . It happened again and again.
I also tried each stick in each slot. Old stick is still working as always in both slot. But with new stick , after entering password for PC user , screen gone black in both slot .
Someone help me please.
