I've began upgrading my home media server so that the main OS drive is in a RAID-1 environment. This involved installing a 3rd SATA controller. While doing so, things were great and moving smoothly. Then, after the third or fourth reboot, the computer began to give 1 long POST beep and never start the boot process. After some troubleshooting, it turns out to be the slot that I installed the card in had went out. I made sure it wasn't the card by putting one of the other working SATA controllers in that slot and had the same result.
The old motherboard was an AMD based MSI brand board. The replacement will be too, but my question is: Since I am staying with an AMD processor and MSI manufactured motherboard, is there any need to re-install the whole OS? Or should I just be able to plug it all in and go?
