I have an older dell inspiron 1130. need to replace the motherboard ram and hdd. what are your suggestion?

I know the MB will probably have to come from dell.

ram and hdd are fairly standardish , you will need a mobo from the exact same laptop (check ebay, i got a new motherboard for my ibm laptop by buying an laptop of the same sort off ebay with no screen and a damaged case and gutting it for the motherboard

yea i thought about that.

How hard will it be to replace though. iv never worked on a laptop before. It may just be more cost effective to buy a new one.

quite hard

if the laptop isnt expensive (not like a sony or something) or its older than 2/3 years, then its probably cheaper to get a new one
