We had high winds early this morning and several power outages. I have a back up battery back up on our PC's, but my wife decided to turn off the PC's after several outages. When I try to boot my Win 7 64 machine I get Nothing. When I hit recovery, I get ACHI port 0 device error. Attempting to boot normally or boot to last known configuration after that does nothing. Any ideas?

You say many times that you "get nothing" or that it "does nothing", but that's a totally unhelpful description. Does that mean you don't even get a BIOS screen? Or that the boot process hangs? (And if so, where?) Or that you get an error message? (And if so, what message?) –  David Schwartz Apr 2 '12 at 18:45

That error is usually a sign of hard drive failure. Use the hard drive manufacturers diagnostics on the drive to see if it is toast.
