audio faster than video when i watch videos online

[cambull]

I have an old computer that I have basically built from parts of a number of other computers. Until a few months ago I haven't had any problems with it, then all of the sudden when I started watching videos online (no matter what website I'm on) the audio started being roughly 2 to 3 seconds faster than the video. Videos saved to my harddrive or from DVD's play fine through my media player. I have unistalled and re-installed the drivers and even uninstalled and re-installed adobe flash player. I've gone online to different forums and tried different suggestions about changing settings and nothing seems to work. I was just wondering if anyone has had this same problem and has any suggestions on how to fix this. I have put the system and display specs below.

Hello and

I would probably start with the topic below....

Computer and browser slowness are not always malware related
