Hi all, knowing that by changing to a new motherboard, CPU and GPU altogether we have to reinstall W7 right? (I've asked some PC shop around some say you have, some say W7 will detect hardware change and do its own bla3) if it does reinstall, Im using the same HDD which is 500GB that has windows 7 ultimate in it already, so if i boot up the pc how will i know it needs reinstallation? And does it eat more space or just reinstall and overwrites the previous files in the HDD? Or is it just better to just reformat the damned thing? Thanks!
How do I reinstall Windows 7 on the same hard drive?

Won't work different chipset drivers are needed.
Clean install is needed.
OEM versions of Windows 7 are identical to Full License Retail versions except for the following:
- OEM versions do not offer any free Microsoft direct support from Microsoft support personnel
- OEM licenses are tied to the very first computer you install and activate it on
- OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard
- OEM versions cannot be used to directly upgrade from an older Windows operating system

Its possible it will detect your hardware. Just right click My Computer, click properties, and that should show your hardware. If it doesn't detect it and you do a re-install. I would suggest "zero" the hard drive, not just reformatting it. Although zeroing takes a bit longer, it ensures the hard drive has deleted EVERY file and it will be just like it came out of the box.

OEM vs. Retail
OEM Windows 7 comes preinstalled on computers. This is the cheapest way to buy windows. Large PC manufacturers like Dell, HP etc. (collectively called royalty OEMs) install windows on millions of such PCs. The main characteristics of such systems are:
The license agreement and support agreement is between you and the PC maker, not MS.
Activation by the end user is not required. Windows is preactivated at the factory by the OEM using images and standard SLP keys.
Your copy of windows is locked to that PC. The license is not transferable.
OEM system builder is what you get when you buy from say Newegg or from a local "white box" vendor. It too has the characteristics of Royalty OEM windows. Although it is possible for an individual to buy a System Builder copy, the license requires that the software be installed using the OPK (OEM preinstall kit) and then resold.
Retail version is what you buy from a retailer like Amazon or Bestbuy. Its a full price version that comes packaged in a retail box with a retail product key. It has to be activated online via MS servers using the key on the box, it is not tied to the PC it was first installed on, though it can only be used on a single computer at a time. And, MS directly provides the support for it. It is also more expensive than OEM copies.
As far as functionality is concerned, theres no difference between any of the versions above, given any specific edition (i.e. between OEM pro and retail pro, or between OEM ultimate and retail ultimate).

Let me get this straight.. Since I know nothing abt this and this is my first time upgrading the hardware for my PC, you're saying that I can just turn on the PC and it'll enter Windows like normal? No weird/crazy/freaky BIOS or anything that demands you to reinstall? Or blue screen stop errors? Thanks!

If so, Must I reformat the HDD? Or is it possible to reinstall on the same HDD w/o eating more space(like overwriting the previous windows installed files)?
Mine is a retail too.

If it's OEM 7 from other computer you will need new license.More than likely won't boot and windows will be non-genuine if it's OEM 7.
