My boss who is a hoarder allowed us to clean out his shop recently. We came across at least 30 laptops running windows xp or earlier(i know haha) i want to build my son a laptop with spare pieces as not one single laptop had all the pueces in it still. I found one witha working screen and used 2 ddr3 and an available harddrive but keep getting blue screen of death.how can i do this the right way
