Help with pc parts

I got a new intel cpu fan and its pin possition doesnt seem to align with holes in the mother board.
Are there difference in holes position in all motherboards??

Also i got 2 new 4gb rams but when i install them my pc doesnt boot. Its boots again when i remove them.??

@sandeep410: can you specify your mobo ?

asus maximux 4 gene z

@sandeep410: what is the brand for the ram you bought ? did you chick the compatibility list , are you sure that you install it right ? the fan connector should be eazy to install are you sure , that you are placing it the right way ? it has a plastic that should sit on .

look at this manual http://www.asus.com/Motherboards/MAXIMUS_IV_GENEZ/HelpDesk_QVL/ ,

My new memory brand is value memory. My currently installed memorry is transced.

Connectors doesnt sem to align with the holes. My old fan gets aligned but the new one doesnt. I can only put one pin in to the hole. Rest doesnt match

Are you trying to install the ram backwards? Also what memory did you buy? is it DDR3 or did you buy DDR2?

This has happened to me. The fan plug had 4 holes and the motherboard had 3 pins. Or something like that. I just googled "using 4 plug CPU fan with 3 pin motherboard" and found how to arrange it so that the right wire was unused. It has worked for me just fine.

By Intel CPU fan, you mean? brand and module?
