Adding RAM creating ethernet driver problem

[Aamir]

Why, when ever i try to add another RAM, my ethernet card (LAN card) settings disappear and it says new hardware found and starts installation of the LAN card (cannot locate the driver).
3COm EtherLink XL 10/100 PCI For complete Management NIC (3C905C-TX)

Move your LAN card to another slot.
Or remove it until you have the memory detected and working properly.
Inspect the card for any thing loose... because it may have connector damage that makes the system think it just found the card... It can also be caused by a loose or defective cable nearby.

i don't know how but all working together again? i think its related more with loose cable or cards.
