Did you try to clear CMOS using the CMOS clear jumper J1D1? Here is the procedure:1. Power down server. Do not unplug the power cord.2. Open the server chassis. For instructions, see your server chassis documentation.3. Move jumper from the default operating position, covering pins 1 and 2, to the reset/clear position, covering pins 2 and 3.4. Remove AC power.5. Wait five seconds.6. Move the jumper back to default position, covering pins 1 and 2.7. Close the server chassis.8. Apply AC power.9. Power up the server.
I performed the steps exactly as requested, and the system still exhibits the same issue.
Any other suggestions?
Try to boot the system with minimal configuration, means 1 CPU, 1 DIMM, video care and PSU only. Then you may need to swap thos components one my one to identify the failed part.
I have done that, including using known good parts from another system. At this point I think the motherboard has somehow got an issue with no way to correct the current problem thus needs to be replaced.
