Can't fix audio lag while watching YouTube videos.

I've been trying to watch videos on YouTube but the audio lag is so bad it's not even bearable. I've gone through everything I can find to solve the problem with no solution in sight, followed all the instructions on the Adobe help page, watched YouTube videos to fix it, updated flash player to most recent version, cleared the cache and data for flash player, made sure all settings were correct, updated the driver on my computer, tried a different Web browser, and just about everything in between. Wound up not being able to update graphics driver since apparently my computer doesn't need a driver to operate... Yet there are settings and I can find the driver on my computer
