WELCOME TO THE FORUMS!!!
...and the sickness
First of all, for your future reference you ought to look at the POST signals in your mobo's manual if somthing similar happens againg so that you dont get a heart attack.
What you are experiencing is a well documented issue with the K8N. On older boards they arent shipped with v1.3 BIOS which officially support the Winchester core....YOUR cpu.
That "beeping" if you look in your manual, is actually "no RAM installed" siren. Its a well documented issue with the Winchester core. Infact it happened to me.
All you need to do, is simply remove one stick of RAM from your machine and boot on a single stick. Without v1.3 or greater on the BIOS your motherboard will not post in dual-channel on the winchester core....THAT is why you are getting the "no RAM installed" siren.
As soon as you boot with single channel, ie one stick. It will function normally. Simply install windows and all that nonsense with a single stick and when you get the earilest opportunity update your BIOS via the interent to the latest version, which I believe is 1.5.
Once you have the updated BIOS install the other stick of RAM and it will function normally without the siren. Its as simple as that
