Thanks. Somewhere I read that the MSI K8N will work with Vista but probably not with Windows 8. I was trying to verify that with you experts! While I built my own computer, I am a newbie. Will most replacement motherboards just fit right in place of the MSI if I follow your suggestion? Any suggestions on a replacement motherboard? (& CPU?) The MSI K8N was pretty quick and I didn't even try overclocking. But I'm not a gamer so I don't need lightening speed, but its nice when pages load quickly.
