New build in old case: Do I need to buy a new copy of Windows?

[bobham]

I am going to be re-building my computer with a new motherboard, CPU, RAM, graphics card, power supply and SSD boot drive. I will be re-using my case, optical drives and several hard drives. I have the Windows7 Pro OEM installation disk that I used 4 years ago to build my existing (but now dead) system. Will I run into activation problems if I use the old disk to do a fresh install on the new system? Is that even a good idea or would I be better to buy a new installation disk that might have a lot of the updates etc. already on it?

Thanks for any help
Bob

A OEM Windows 7 is not transferable to another computer that has the items you listed replaced.
If you had a full retail version of Windows 7 you could move the operating system as long as it is only on one system at one time.

Okay, thank you, that is exactly what I wanted to know.

Thanks again
