Hi everyone ive got a Gigabyte Z77-D3H motherboard and i was just putting a new graphics card into it and noticed that the CPU wasnt seated properly because one of the clips had come away from the board.After reseating i when i booted up the pc i got a a load of beeps.When i looked into it it said that it was a memory problem.So i swapped the memory around because i was running 2 sticks in dual mode and it would appear that slots 3 and 4 arent working properly.Has anyone got any ideas why this had happened and does it mean im going to need to get a new motherboard if i want to run more than 2 sticks of memory?
