I'm guessing you did not install the Notebook System software, the chipset driver, the video driver, the network card driver, and whatever else drivers you need for your laptop.     Once you have Windows re-installed, use a flash drive containing the drivers downloaded from another PC.
Ok, this will take a while, so bear with me. I have a Dell inspiron 9300, about 5 years old. Everything, including internet was working fine. Except, it was really slow. I had zillions of files and unwanted programs. My CD drive was on the fritz too. I reinstalled xp, (somehow the drive worked long enough with the reinstallation DVD). When It was finished, the computer was much faster, but, I couldn't watch movies, listen to music, and intel proset wireless just had a shortcut, nothing else ( likes i said it was all working before, just really slow). So I put in the driver CD ( i had to use the external drive this time for some reason) and downloaded the ones it said i diddn't have. It still is not working!! I need to at least connect to the internet long enough to perform all the update, and get all the drivers. But the only thing in internet connections is 1394 connection!!! help please!
