Newly built PC shutsdown during startup

[fasnuki]

I just built a PC but it constantly shutsdown during startup. It displays the RAM, CPU, and HD; then it simply shutsdown. The last onboard LED to display is "75." The hard drive has XP loaded on it. Just looking for some ideas and suggestions. Thanks in advance.

Not an answer but a very curious look at that error number:

EISA-interface error

Remove all PCI Cards. Clean, and reinstall in the system.
If error still appears possibly faulty PCI Card.

I removed all of the PCI cards, now i receive the CMOS Checksum error.

Load CMOS defaults
