Hey i have a problem for some while with my sound i have realtek ac97, the problem first started when i was watching a movie and slowlly the sound was starting to disintegreate(dont know how to discribe it sry my english is bad), and then i had no more sound.....and my pc rebooted.... After i started my pc i had perfect sound for about 5-10 min. and then my pc will reboot again, i tried reinstalling the sound driver but nothing happens my volume icon is gone, i had to desable the sound from bios so i could use the pc. I reinstalled windows(XP SP2) and now i cant install the sound driver in any form.Please help!

Since you had to disable the sound in your BIOS, you may want to find a separate sound card, install it, and see if you get sound. If you do, that means here may have been a hardware failure of your built-in sound.
I would also scan your PC for viruses - maybe that movie was infected.
Also, the most current Service Pack for Windows XP is SP3.
As a last resort, please post your system specifications and we will go from there.
