Sound not working. At all.

[Phillycj]

My sound hasn't been working since I installed more RAM/added an external hard drive to my Ei System Ei 106 PC. I had REaltek audio drivers, but they seem to have gone since the upgrades. I'm trying to get audio back, but I can't. Can anyone help me?

Do you have the correct drivers installed?

If drivers are good then run fix it from Microsoft's website.
