What kernel fully worked for you last time?

In the BIOS (must be something APIC related)

Can you grab dmesg and save it somewhere? Without boot log there's
noone, who can help you, i guess.

You need ordinary female-female(2-3, 3-2, 5-5) RS232 cable, or
USB-to-RS232 cable. Serial console is activated by 'console=ttyS0'
(default bautrate is 115200, i think, see more in
Documentation/serial-console.txt).

Try some older kernels also.
