i guess you did not check the compatibility of the RAMs to your MB limitations....
the only solution is to return the RAMs and get the RAMs that is supported by your MB.....
the MB (D102GGC2) can hold only a max of 533 mhz and max of 1GB each in each slot of RAM....
so if you are trying to install one 2GB card of 800 mhz IT WIILL NOT WORK....
get TWO RAM cards of 1GB each (total 2GB) of RAM.... each of 400 mhz....
hope this helps...
to check what your MB supports, look for the details below...
