Z420 beeps 6 times when startup



I use HP z420, which have no graphic chip onboard.

I use one graphic card inserted in PCIe slot.

I just setting the bios to disable all the PCIe slots stupidly.

When I reboot z420, it beeps 6 times, once every second.

According to the manual, it indicates the Pre-video graphics error.

Is it because I disable the PCIe slots, and how can I enable them?

You may also want to post your question on the HP Business Support Forum, z Workstations section.


If it were me, I would shut down, unplug everything connected to the PC (keyboard, monitor, mouse, etc) and reset the CMOS.


There should be a little yellow clear cmos button on the motherboard somewhere. 


Press and hold it for 30 seconds and then put everything back together.
