Dell laptop problem

Hello, my dog just recently knocked over my dell latitude d630
and now when i try to boot my computer it blinks a blue screen and then restarts : ( i have no time to look at the blue screen but i have done a diagnostic test and found out that it is a memory error
im not completly sure what to do when i take my computer apart to fix the problem because ive only worked on desktop computers before
it has shown a memory status error 70
it would be very helpful if i recieved advice thank you
please email me at zelth101@hotmail.com because im using a friends computer to post this
