"02FA Machine Check Error on AP" Sun Java Workstation W2100z

I have a Sun Java Workstation W2100z, at the preboot displays this messages:

"02FA Machine Check Error on AP"

F1 for continue or F2 to run setup, after press F1, the system is Up baut 10 minutes later it reboot. I have Windows Server 2003 32 bits.

Any comments?

Thanks a lot...!
