I have performed more testing and can further specify the problem I am experiencing.
Sleep Mode. The computer will go into sleep mode, but on waking will not reconnect to the internet (I have a direct cable 20mbs connection).
Power On / Power Off. The computer turns on and off without any trouble, and connects to the internet once on.
better go back to 5200 bios if you do not have ecc memory. The 5314 bios has some isseus and doesnt overclock well You can install 5200 bios over 5314 with no problems, did it myself. , Running again at 215 BCLK
In your BIOS do you have it set to S1 or S3??
Thanks for the replies, and apologies for not updating this thread.
A day or so after I made the post, I chatted with an Intel Technician who said my problems were not uncommon with that release. I was given a link to a previous bios which I installed. Since installing a previous bios, no problems have been present and the original problems warranting the change in the first place have gone away, too.
Thanks for the replies.
