I am pretty confident in my diagnosis, but I will get other opnions too It has green lines at the XP boot screen and it freezes at the login screen which was not present on the other computer we tried I put the drive in the laptop and it did not work the same, it just froze up on me Wireless doesn’t work(this is a warning based on what I read before getting this)
Wireless has nothing to do with it. Hook it up to an external monitor and watch that monitor for artifacts on it. Try starting up in Safe Mode first and note the externals behavior. Then try your system installation disk. I have not seen the Nvidia issue produce green lines. I’m not even sure HP is still replacing this, they’re not Apple service!
