I boot up my computer today and up pops a message about my bootmbr being missing. I, figuring this was quite bad, stuck in the ol' vista installation disk to run a startup repair. It does its thing, says its successful and tells me to reboot. I do, and get a new message at startup, saying,"Windows failed to start. A recent hardware or software change might be the cause...

Info: Windows cannot verify the digital signature of this file"
So I figure I'm getting somewhere, load the disk repair, and I get "Startup repair could not repair the problem." along with other steps i should take to "send it to microsoft"() So now i run commands like chkdsk /p,bootmbr,bootfix (I've done this before). NONE of these do a darn thing to solve my problem. (Ive done the F8 thing with the load drivers w/o signatures; didnt work.) So, I figure i should take matters into my own hands. So i open up a CMD, and copy a ntkrnlpa.exe from my install disk and replace it with the one on my hard drive. Logical? I thought so. But same results. Except for one thing, when the repair thing runs again, the details say that the file "pshed.dll" is corrupt. I replace this one, doesnt work, and then says the ntoskrnl.exe is corrupt too.... I replace this one as well, but this one has remained corrupt. I sometimes get a new message when running the startup repair. System volume on disk is corrupt. But other times I get "Boot status indicates that the OS booted successfully." So Ive pretty much used all I can think of, short of booting BartPE and copying my important files and reinstalling. One more thing that happened. Last night (when everything was running smoothly) diskeeper did a boot time defrag. I think something went wrong and this is what is causing all this trouble.
