System Fails to Boot (Deadlock?)

[Brandon Falk]

Hello,

My machine somehow fails to boot into FreeBSD (off the cd, since it 
fails to boot, I can't install it in the first place). It goes through 
and ends up stopping deadlock style. No printouts of errors (besides a 
ppc problem, which is not fatal) and no crash/oops/panic. It just... 
stops and locks up. I know my motherboards PCI system has failed, as 
well as lan (getting a new one tomorrow), which is probably what is 
causing the problem. The thing is that Windows 7 and Linux happen to 
boot just fine on my machine, so although my system has a failing 
motherboard and may cause errors, I still feel like it shouldn't be 
causing this much of an issue on boot. I tried verbose logging and got 
no more information anyways. It will be nearly impossible to diagnose 
this error so I'm looking for tips on where to look.

I'm an avid programmer and I could fix the problem if I were able to 
find it. I could just compile custom kernels to give printout and debug 
messages every step, but that would be a long process if there is a 
better way. Keep in mind I do not have FreeBSD installed, no serial or 
parallel ports, and I'm booting from a CD. Once I get the new 
motherboard I will probably not care about fixing this problem, as I'd 
be replacing it. So this is more of an overnight deal that I'd like to 
look into.

System:
Intel i7 970
24GB ram
Asus Sabertooth X58 motherboard

If you need more system info, I'd be glad to give it.
