During the boot sequence the computer gets stuck with the error code 15 ("Pre-memory North Bridge initialization is started."). After 15 seconds (more or less) the boot sequence restarts. My memory cards are inserted in the grey slots (DDR3_1 and DDR3_3). Also I`ve inserted only one at a time in DDR3_1 and I get the same error.
2x8 Gb memory cards compatibility checked (Corsair CMZ16GX3M2A1600C10)

It seems some mobo problem, but i don't know if I can configure something.

Some ideas?
Txs in advance.
