Hi, my friend is finally building his PC, I was thinking if we would have to format his windows 7 since he is gonna replace all parts other than HDD. So do we have to? His PC now is very old... But the HDD is fine. Must we format it and install windows 7/8 on it again? Thanks!
Yes, When installing a new CPU and mobo , a FORMAT is a MUST ,
Especially when the HARDWARE is old.
I learnt this the hard way......
When i upgraded my PC , It wouldnt boot up , and i disassembled and re-assembled it twice ,
until a friend told me that the same happened to him and he had to format his PC.
