I was trying to revive an old computer that had its CPU and power supply go out, but I ran into a problem that I can't seem to figure out.

The computer is running a: 2.5ghz p4 celeron (replacement)
Soyo P4I 845PE Lite Mobo

I plugged in a wiped hard drive and tried to install windows 7 from the dvd drive. I got a boot bcd error 0xc00000e9, which says that windows has a problem with communicating with one of my connected devices. Thinking it had to be either the dvd drive or the hard drive, I tried replacing both. I replaced the dvd drive and I got the same error.

I decided to pull a hard drive from another computer running windows xp and booted from the hard drive and it gave me a BSOD STOP: 0x0000007B error. I tried to reformat the 2nd hard drive with Windows xp on it, but I got the boot bcd error 0xc00000e9 again, which makes me think it isn't the dvd drive or the hard drive since I get the same errors when replacing either.

I tried hooking everything up to a different motherboard and the BSOD with error STOP: 0x0000007B comes up again.

I'm out of ideas, can anyone help?

Well easiest thing to do since you have access to spare parts is just try the only 2 things left to swap out, the ram and psu :)

Set the BIOS to default and try booting. Make sure nothing is overclocked. Also do a memtest. Hiren's Boot CD has some good hardware testing utilities that you can use to hopefully diagnose a problem. Disconnect all unnecessary devices when doing your testing.

Well, at least that one's not mysterious. That old Windows XP installation is looking for a different disk controller than the one that's on the new PC. An XP "Repair Install" (NOT a re-install) will usually fix that problem.

You can also boot from the UBCD4Win disk and there is a 'fix hard drive controller' under registry tools. It takes 2 seconds, updates the hard drive controller driver and fixes that problem.

A repair install also works, but takes a lot more time. I've used the UBCD4Win dozens of times to fix that problem. :)
