Hi well there is one thing to try which might help. Reboot in safe mode, you can do this by tapping the F8 key after rebooting. Start tapping when the screen goes blank. Choose #3 safe mode, and when in safe mode open the device manager. Look for any duplicates under ALL listing except for systems devices. If any duplicates are found remove ALL instances of said devices, when done restart the puter and windows should install said devices. Make sure to do this in safe mode as normal will not show duplicates. Let us know if this helps.
i restarted my computer today and when i turned it on an 'installing new hardware' window opened and I had to reinstall my sound card driver as if i had never done so before. it said that it installed correctly and etc, but now i dont get any sound. my speakers are all plugged in correctly and are operating find, and no channels are muted. music and video files will open and run properly, just without sound. i am running on windows98se. thanks for any help.
