Boot failure on a Dell desktop

I was working on a clients PC that was struck by lighting.  I replaced the PSU, Mobo, RAM, and VGA.  The system receives power(i.e. drives boot up, power light comes on, motherboard light comes on) but the monitor does not receive signal, and I get no beep codes.  The last step is the CPU, but before I order one, I wanted to know if there was anyone here that would have anything else to try.  The system is a Dell Demision 4500.  I did make sure to buy a Dell "authorized" PSU before installing it.

Thanks for any and all ideas.

I think you've answered your question. That's the last piece of the puzzle. Barring some extremely odd power outlet issues (which I highly doubt) it would seem to me that the CPU needs to be replaced. David

    After conferring with another colleague I started removing all the pci cards and found that one of the PCI cards was causing the problem.  Thanks for posting.
My bad. I was under the impression that those cards were removed. I assumed that when I read that the video card was replaced. If you're still around, which card was causing the issue?
