This could be something as simple as taking the CD out after installing. If your system is set to boot from a CD first and it finds a disk that isn't bootable, it would stall the startup. You can change the boot options in the BIOS settings so it boots from the hard disk first. but in the first instance, just take the CD out and see if the system can start.
What make and model is it and what reaction does Windows throw up when it's plugged in without its disk? Windows 8 Pro should be able to find a driver for most popular makes of wi-fi adapter without using an installation CD. It's possible the adapter's manufacturer wants it software to overarch Windows own wish to take control.
A few of my wifi adapters had the same problem. But when I installed the drivers from Windows safe-mode they worked.
Thanks dude. after looking around, I found out that it probably is my disk causing the problem. Apparently, the disc only contains installation for windows 7 and older. might as well get the driver online then. thanks though.
