I am back to this forum. After year of usage, my Z9PE-D8 started to give me some problems. It is very difficult to boot. Sometimes I have to restart the Workstation several times before it boots.
The motherboard gives error d7. Please notice that after it starts, everything runs smoothly as usual. So the problem that I have is that the PC won't start randomly for a number of times, than it will boot and run fine until I turn it off.
Error d7 is officially listed on the manual as: "no console input devices are found".
I changed mouse, keyboard, other USB devices (I removed them all) but nothing changes. The system simply refuses to boot for a number of times and then, leaving all as it is and forcing reboots, at a certain point it will "magically" boot without errors.
During usage system is very stable. I can run 48hrs or longer analysis (COMSOL, Ansys, etc) without problems and smoothly.
I tried to search for this error code without luck, I'll try to ask Asus directly. It seems that it can be related to PSU problems (12V connector) but, as I said, after boot I can run 100% CPU for hours without problems.
I didn't change a component in the last years (this workstation is from 2014, I updated RAM and moved some components in 2016 probably) on this built and I never had particular problems.
My setup is:
2 x Xeon 2687 v2
8 x 8Gb hmt31gr7cfr4a-h9 (ECC RAM)
Quadro K6000 (tried to change it, nothing changed)
Sound Blaster ZxR (tried to remove it, nothing changed)
Enermax Revolution 85+ 1250 Watt (very old PSU)
APC Smart-UPS - SMC1500I (or similar unit, I am not 100% sure about the exact model)
Does anybody have similar experience with this error code? Thank you!
