problems after downloading windows xp service pack 3

I recently downloaded service pack 3 on my advent T12. It seemed to download very well and when it restarts automatically he started very well too, but when I tried to restart it then the log on screen did not appear; It started to load as usual and the screen with the windows logo appears, but then after that it was just a black screen, if the computer was still running. I was able to boot in SafeMode ok and took the restore point. After that it restarted again as usual, but I have no sound. I have a device high definition audio C-media. You can hear the sounds system, but nothing about DVD or music files. When I go to Device Manager it isn't even an audio device listed. I tried to download the driver from the microsoft update catalog, but I have no idea what to do with a .cab file once its downloaded. Whenever I restart my computer, looking for a PCI device it says that it cannot find the software. I've downloaded SP3 again and when I do it locates new peripherals - audio on bus high definition audio and successfully downloaded the software and I have her again but am back to the problem of having no log on screen! This time I uninstalled SP 3 in the Panel, and he warned me it would be it would cause a problem with the audio device. So I can SP2 with no sound, but the computer starts very well or SP3 with the sound, but it won't restart. I searched and searched on the internet and on the site of microsoft for some answers, but I'm a loss. Please can anyone suggest a solution? I'm not overwhelmingly technical. Thank you
