I would start by eliminating as many davices as you can, but still be 
able to boot linux and have a console.
One thing you might try is eliminate the graphics card and use the 
serial port which you connect, via a null modem cable to a second PC - 
where you can then run minicom on the second port's pc to capture the 
failing pc's output. minicom allows you to capture everything into a file.
If you do not have any PCI cards and all your devices are built into the 
motherboard, you might then try to disable them in BIOS if your BIOS 
provides such a feature. For examle, some BIOS'es let you disable USB 
chipsets, or disable the raid and use the plain or plain sata.
Hopefully you get some more info.
