had xp already set up in my c drive, which was acting funny,? and found a lot of trojans (which are deleted now) after running an avast antivirus scan. so, i had another xp installed in my f drive. so i have 2 xps in my computer, and i prefer to use the newer one in f drive. however, i'm unable to play sounds in the xp in f drive. when i go through the settings; it says it does not detect any audio hardware?! but when i use the older xp in drive c, it has the same settings it used to have before, detecting my headphones and i can hear music and play sounds in it. now the problem is that..i have downloaded a movie from Ares and i want to watch it. but... if i watch using my newer Xp in drive f:, i cannot hear sounds, but only view the video. and if i watch in my older xp in drive c:, it is showing some kind of error message in all players (some codec error), and im not able to watch the video but can hear the sound well. i have tried, winamp, win media player version 9..etc. what do i do? Additional Details 1 day ago i did not 'separately' install any drivers while installing the newer xp in drive f. i was told that the drivers are included in the cd. i tried the hardware detection part and everything as such..in this newer xp in drive f. but i just cant seem to be able to hear any sounds!! what do i do??! plzz..heellpp..... 1 day ago thank you all for the answers.. now when i checked on the older xp in drive c; hardware options: i can see "realtek ac 97".
