Hi, My sisters laptop is not working correctly. It is fairly new, she got it about a month ago. It is an Acer laptop, model #: aspire 5570z, with Windows Vista Home Basic. processor: INtel T2060 @ 1.6GHz, ram: 502MB, and is 32-bit OS. The problem is that the dvd disk drive is not showing up in my computer, this problem happened yesterday randomly. After seeing this i went to device manager and it showed up so i went to the properties of it, and it says: windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available. So I tried this, and nothing happens, it just comes up with a box that says sending solution with a little loading bar, it loads, then it goes away.
