[PurE GaminG]

hi guys this may be a daft question but im not sure of it so i just want to make sure if it can be done.

ok you see im making new rig and selling mu old rig in components bits. i want to keep my 1tb hard-drive winch has windows 7 os in it

so my question is would it be possible to transfer the hard-drive on my new rig with the os still on it and will it work on my new rig or will it have conflict with new mobo and cpu.

look forward to ur reply's
