    Hey Chrissyo,
    Ive tried all the driver updates and rollback options but i can't seem to get it to work, a friend from melbourne told me that it was a problem with the mainboard not being able to cope with a newer style DVD drive and software, ive gone into my bios and changed the settings to UDMA 4, but when i'm in hardware manager it still tells me it's running on PIO mode even though nero tells me it's on ultra dma.

Oh mind you that other computers or systems are only designed for Windows XP and the Drivers that are installed on that machine are XP compartible. Now that you are using windows 7, it could be an issue that Windows 7 operating system does not recognize the device being your CD drive.. You need to go on the HP official website and look for the drivers (the whole packge ) for your computer model and check if Windows 7 operating system is compartible with the machine. Otherwise the solution is to go back to Windows XP...
