The component is a tantalum capacitor.
It should probably go with the white stripe to the left. Why? because thats the way the rest of them are. It is good practice to orientate all all polarised components the same way. This is too make inspection easier.
The value 106 is the capacitance in picofarads (pF) where the last digit is the number of following zeros.
ie. 10 with 6 zeros. 10,000,000 pF or 10,000 nF or 10 uF
From the picture it looks like the cap was intended to decouple the not fitted IC. However I don't know what's on the other side. Either way it is extreamly unlikely that replacing this part will fix any problem this card may have.
