Onboard sound input latency problem

[SexyGreyFox]

My Audigy 2 has decided to not work properly so I've switched on the onboard sound on my M4A785TD-M EVO motherboard.
The problem is I plug my guitar into the aux in and I have a delay.
Any ideas what I can do?

I wish you told me this when I asked
I ended up buying a £37 Audigy from OCUK which my motherboard wouldn't recognise but after a few things going wrong with Win 7 I decided to start again and my old Audigy is working.
