Do i have to reinstall Windows?

[RegMin97]

Hi, i'm upgrading my pc by changing the motherboard, cpu, ram, graphics card and power supply. After the upgrade, will i need to reinstall Windows 7?

Yes you will need to do a fresh install of your windows 7.
Since the chip set of the motherboard will most likely differ from the old one.

Any attempt to use the old install of windows 7 of the existing hard drive will result in a blue screen of death since all of the drivers installed will be for the old board you had.
