Need help in PC compatible parts.

I got these part and was wondering if it going to be compatible with my pc. It is a Dell XPS 420. The comp is very old. So ofc, I need to replaced most parts in it.
Here are the parts:




and here is my current PC model & Info:

My friend confirmed that the 5 parts above are gonna be compatible with each other as well as with my pc. So I just wanted to double check.

Another question is, after I replace my motherboard, do I need another operating system?
My current window is window 7. It is a retailed version. However, I don't have the activation code nor the disk for it. Do I still need to purchase a new operating system?

Any help will be much appreciate.

  1. Another question is, after I replace my motherboard, do I need another operating system? < YES the OEM DELL OS is tied to the Dell motherboard.

    The motherboard , memory , and PSU aren't good.

    All the hardware looks compatible.

    Run Belarc Advisor and you can back up all you licenses, including windows.

    Yeah, my mistake.
  6. It's just easier to read , Thanks.
  7. thank for the replied all. And wow, I didn't know you can compared prices like that. This is a new learning experiences for me. Also the reason why the motherboard, psu, and memory aren't good is because I likely picked the cheapest out of my budget on newegg. Both psu and motherboard are recommended by a friend (as they also know my budget). Next time if I ever try to build my pc again, I will carefully pick the parts more.
  8. CX series power supplies are made with cheap capacitors and Biostar makes very poor boards.
  9. kjatt is wrong , you can't use the windows license it is OEM. :(

    With windows 7 OEM the license is tied to the first motherboard it's installed on.With Windows 8.1 you can move it to another build when you are done with this one , but only one computer at a time.With Windows 8.1 you can change all the hardware you want including the motherboard.

    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 ^

    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).

    Windows 8 is a whole different ballgame.
