micron millenia gibralti board
pc working fine all day, screen blanked out, power panel sleep mode (moon) amber light illuminated, while computer still on (fan running). restarted via hard reset, pc started, then exhibited same symptoms. re-seated video and SRAMs. pc will power on for a minute or two, load winxp, then go to sleep mode with blank screen. Pulled power, waited 30 mins, pc powered up and again with sleep mode.
PC does not have diagnostic LEDs.

The PC is intermittant, ususally after two hours of wait time, I can boot, go through auto scandisk/chkdsk, backup a few files and then the CPU fan stops, followed by the case fan then the motherboard and all components power off. There are two lights near the power button, one amber the other green. When the PC shuts down, the green light extinguishes and the amber light (moon) illuminates. I can press it for 5 seconds and the amber light extinguishes. After that the PC does not respond other than the amber light on and off. The mother board has a green LED (CR6FI) that stays illuminated while I have the power cable connected and goes off when the cable is unplugged.
Additionally, I changed the CR2032 watch battery, swapped the AGP video card for a backup PCI video card, ensured all SRAMS are inserted and seated, unplugged the power lead to the mother board and reseated it back into the motherboard, all to no avail.
Thanks again epr1977
