well recently i have decided that i mite take a carrer in fixing
computer because i am about to leave school

and so on and so forth

my laptop broke and before i could send it to the shop i took it all apart and took the ram , HDD etc. out and then back in and i was
wondering what would happen if i started it without a HDD because

the ps3 it wont start it says something about the hdd (cant remember)

thanx in advance
