Try uninstalling the sound in the Device Manager(do not uninstall the drivers), then restart the PC and when Windows starts it should detect and reinstall it. I've seen problems where a new device has caused another device to not start and doing the uninstall/reinstall fixed it.

By uninstall the sound do you mean uninstall the device if so i have done that 5 times over to no avail

I understand that I am a few months late, but I had the same problem with my Radeon HD3450. What happened with mine is when I installed the new video card it installed a sound driver to put all the sound through the HDMI port that wasn't there unless I had the adapter. The HDMI driver disabled my On-board audio, so I had to go back into the BIOS and re-enable it. I hope this helps if you haven't found a solution yet.
