Check your laptops specks for your Primary (A) slots and make sure the large (2GIG) chips are in them. I believe if you have slower ram in the other slots(B) It may degrade the faster ram to run at the slower speed of the older ram or cause boot problems.
So remove old ram and install new ram to primary slots and reboot.
If everything is good shut down and reinstall the old ram only if it is the same speed or you don't care if the new ram runs a little slower. Your probably better off selling the old ram or trading it in for new+ a few $$

Good luck
