No drivers/internet/ethernet port to connect to wifi

So this might be pretty long but this is all that has happened so far. So my laptop which is a HP DM4 it was fine nd everything but it would shut itself off but i had it plugged in and everything then when i went to turn it bck on it said to put a recovery disc so i went on my mom's laptop nd downloaded that nd burned it and used it. It reinstalled Windows 7 but when it would boot up it would look like Windows 7 but the log on screen nd home screen would look like Windows XP so i been downloading drivers since i dnt have most the stuff i need nd i got Areo nd it looks like Windows 7 again but the clock nd those icons still look like XP like it shows a computer instead of wifi bars. So problem is now that my internet button doesnt work for wifi nd there is no networks to connect too nd some drivers are missing which ive tried so many things nd not getting anywhere. Idk what i did though but out of the times i was trying to download windows 7 i finally got windows 7 home premium up but it was all black nd said it was an ungenuine copy nd was on a temporary account nd everything would get deleted after logging off. After i shut dwn it made me reinstall windows nd now ive tried to get bck to the black screen one but it just goes ito the XP looking one.
