Computer will not load any operating system

I'm at my wits' end trying to solve this computer problem. The system will not boot to any OS install CD (Windows 7 Pro x64, Ubuntu 9.10 x86, Ubuntu 9.10 x64) even after a total hardware replacement.

Lightning struck my friend's electrical system, destroying several appliances and allegedly causing her first-gen AMD Athlon computer running XP to lose keyboard and mouse functionality.
Keyboard worked fine in BIOS. I tried using a Ubuntu 9.10 LiveCD to confirm this wasn't some Windows driver nonsense but the system would freeze before I actually got into the OS; the keyboard worked long enough to select what I wanted to do (boot the LiveCD environment) but after I selected it I would get an I/O error: could not read from disc. There is minimal activity going on with the CD drive while this is happening.
Tried other installation media. Same result.
Replaced the CD drive with a new DVD drive. Same result.
Unplugged all unnecessary peripherals (floppy, hard drives, etc). Same result.
Since I had no way to test anything at this point, I assumed lightning trashed the PATA port. Replaced the motherboard, CPU, RAM, and video card (they were overdue for upgrade anyway).
She's on completely different hardware now and I'm still getting the same result. I have gone the extra step to upgrade the PSU, being one of the two original components left, yet the problem persists.
At this point the only piece of hardware that hasn't been replaced is the case. I know my install discs are good because they work on any other machine I put them in.
The Windows 7 installer will go through the DOS-looking "starting installer" phase until it gets to the artsy Windows 7 blue screen (not a BSOD) and then freezes.
Both versions of Ubuntu get to the screen where I select what I want to do (I select "Try Ubuntu without installing anything") and it gets hung up at that point.
Any suggestions before I start getting premature hair loss? Could the case possibly be the culprit? It's the only thing left now but I've never heard of a case causing this type of problem.
