i got this Intel Core 2 Duo with motherboard and ram. It's belong to my parents pc. I think it got fried up, when I brought the pc to the store, the technician said they had to replace all (cpu, motherboard & ram). They never told me what's the problem. When I try to on the pc, the cpu fan spin up but there's no display at all. Can you guys tell me, what's the problem with it? I'm bad in explaining
