I got the motherboard back on Tuesday. It took me about 70 minutes to plug everything back in. I powered up the computer and it has not given me a problem since then. Though, it still makes a slight chirping noise when I access the computer; I am pretty sure it's not the hard disks.
For the moment, it looks like there is harmony among the components. I bought the rig about three years ago, yet I don't have any compelling reason to upgrade. As long as nothing in the PC croaks, I'm sticking with this setup for at least another year.
To all my readers (yes, both of you), sorry for the depleted blogging in April. I'll make up for it in May.
