It sometimes works out that you might still be able to ssh in from a 
remote machine and get some logs/dmesg, run top.

On a Dell Poweredge 750 {and I think other models see Dell forums} with 
FC3, if runlevel 5 was used or started, then an X process would go 
99-10%, making the machine severely slow. {It required a reboot to get 
around this condition}. Just a thought.

You might also be able to leave some xterms open running top and tail -f 
/var/log/messages to see if anything is being logged.

Another thing to try would be a serial console, since any emissions 
before death would then be easily captured. Boot with 
console=ttyS0,9600n1 or some such and fire up minicom on another machine 
and use a null {crossover} serial cable.

Good luck.
