Hi, I have an Acer Aspire 8930G which was originally supplied with Vista. I then applied for the free Windows 7 upgrade which I received and installed. Following that it has been running fine over the past year but I have recently had problems with it on boot up, until last week it wouldn't boot up at all. I therefore decided to boot from disk (using the Acer upgrade disks supplied) to see if the recovery would solve the problems, but had no joy. I eventually decided to reinstall Windows 7 using the upgrade disks?? Now, Windows 7 starts up, but I have no drivers installed?? I have also noticed that a new file has been created on the C drive named "Windows.old" (60 GB) which contains all my old files and software?? I am not that bothered about keeping my old files and would like to totally wipe the hard drives to bring it back to the Factory settings, however the only disks I have are the Windows 7 Upgrade Disks, one of which does contain the required drivers but will not run or install them?? Please help!!
