You mean autimatically? Do I have to have an internet connection to do this? --- HDD & RAM are fine since Windows XP works flawlessly on them. I also run the Memtest86+ and there were no errors. Now... First I tried (unsuccessfully) installing the Video and Audio driver and then after a reboot the PC started rebooting by itself. I went into the safe mode and (this time successfully) installed both drivers there. But after the reboot the rebooting started again. Windows is only stable if I go into safe mode. I tried uninstalling, reinstalling drivers etc., nothing helps. Any ideas? Here are the Device IDs of the missing frivers: PnP Audio Device: (It's the C-Media Audio Driver - for Vista, that I downloaded from ASUS site.)

I'm officially done with trying to install Windows 8.1 on this particular PC. It's totally f***ing unstable. I will install XP, thank you all anyway!
