Hi first i tried to install a disk of windows 7 i had laying around before that i had windows vista and i did do i full complete format of my hard drive before installing my windows 7 after install was complete no errors or anything i now have a huge sound problem not that bad as before ive managed to fix some of it. I downloaded the latest driver that didnt help made it worst then i downloaded a driver program that looks for driver updates for you i had like 15 that i updated i then said windows xp is old lets try an older driver that helped a lot!!!! i then went into my sound control mixer thing and i turned down the wave alot!!!! like its just barely above the mute line and that really helped but now there is only a certain loudness i can go up to which in reality isnt that loud its like night time sound... any thoughts please dont tell me to update drivers ive tried latest to oldest and the older ones really helped
