This is how I would recommend doing it.
1. While in Windows, insert the installation disk and then immediately shut down, ignoring anything that pops up from having inserted the disk.
2. Disconnect the current OS drive.
3. Attach the SSD to the SATA 0 header on the motherboard using the cable that comes with the drive. Your older drive may have a SATA II cable rather than SATA III, which could limit the drives performance.
4. Connect power to your new drive.
5. Turn the system on and press whatever keys are necessary on your system to enter the bios.
6. Once in the bios, designate the CD/DVD optical drive as the primary boot device if it is not already.
7. Save settings and exit the bios. System should boot to the windows installation disk.
8. Perform a clean install, as follows:

9. After installation is complete, restart and enter the bios again. Change the primary boot device to the Windows drive. Save settings and exit.
10. Boot windows and install any necessary drivers (Might be a good idea to download any network adapter drivers before doing any of this, and saving it to a USB or optical disk in case you need it. Other drivers too if you wish. Windows doesn't always have the necessary drivers natively.)
11. Download or install Magician and update firmware. Install any desired applications. Done.
