I am replacing a motherboard and cpu in a pc, with 2 hard drives full of important data and i have been told that i must install a new operating system on one of the drive for them to be able to work on this pc. Is there a way i could fit the board and plug everything in and use the operating system already on one of the HD's or will i have to install a new one?

Don't think you will have to install a new operating ststem. If you're using WinXP you will most likely have to re-validate the OS with MS.

I'm afriad you will have to reinsatll an operating system to get your PC to work.

I'm not sure of the exact technical reasons but apparently the operating system recognises which motherboard and other critical hardware were present when it was installed and if this changes it just wont load.

The other thing is if your using windows XP for instance and it's an OEM version it techncally dies with the motherboard it was first installed on and may or may not reactivate on your new board.

Sorry to be the bearer of bad news but mayby an entirely new PC may be a better option if slightly more expensive.

if you have the xp cd try booting from it and then take the option to repair the installation. If you are lucky it will go through and set up for your new mobo. You have nothing to lose doing this.

Probably won't boot due to wrong motherboard drivers.

try booting to safe mode then remove drivers

before rebooting and installing the drivers that come with your new board.

with howard64 on this.occasionally you can get away with a repair but most of the time it's a reformat job.
