Networking problems after power failure

So everything was working fine until I lost power at my house. When I powered on my amahi server, I had a boot message that said dhcpd failed. When I started investigating I found eth0 was down. Every time I reboot I get the same results. I ran through the Amahi interactive network troubleshooter and this is what I got:
Using the Network Troubleshooter, I failed step 4 - DNS resolving for internal hostnames. Here's a paste to help troubleshoot:

Any help would be greatly appreciated!

Is your router working?
Can you reach an outside IP address?
Try:
ping -c 1 8.8.8.8
It should succeed with 0% packet loss.

Yes, router appears to be working. However, no internet connection for the amahi server. I have internet access from my win7 machine and can ping 8.8.8.8 as well as my router's external ip. But no luck from the amahi server. When I try to ping 8.8.8.8 or my router's external ip I get the message "connect: Network is unreachable." The amahi server can ping my internal gateway ip and it can ping my win7 machine.
Any other ideas? Thanks

Have you checked your error logs for anything obvious? (/var/log/messages)
If you haven't looked at it before, I suggest starting at the bottom of the file and work upwards looking for errors related to networking.

Well, things have gotten worse. I rebooted the machine and now it won't even restart completely. It just freezes at the fedora splash screen.
What would be the best thing to do now?

Sounds like a disk or hardware problem.
Can you boot in single user mode? If so, I would explore the error logs to see what might be causing the problem.
You might try booting the system with a live cd. Mount the root drive and look at the error logs (in /var/log)
If you can, check the disk SMART data to see if your drive is dying.
