Is my memory slots broken?

[toast245]

Hi,

I have a evga nf66 motherboard. My memory slots go white/black/white/black. Any memory that goes into the first white and black slot will make my pc not boot up. The fans run, cd drive works, etc. If I place my memory sticks into the last white and black slot, the pc will run perfectly fine . Because of this, I can't dual channel. Is my memory slots just faulty?

I'm using KVR800d2k2/4gr. 2x2 gb 800mhz.

To run in daul channel mode you must use the same colored slots. Either use both white slots or both black slots, not one white and one black, and see if it runs fine.
