Hi,
I am trying to build a PC using a Z87 Pro4 mainboard and i3 4130 CPU (new, listed as supported with the initial BIOS). There is no reaction when trying to power on the system: no beeps, not even the PSU turning on.
I removed all extension cards and RAM as well as all cables but the main/CPU power cables and PC speaker/power on connectors, still nothing.
In order to make sure the power switch is not broken I connected the reset switch to the power-on pin, still nothing.
I tested the PSU by bridging the green and ground wires and it turned on.
After this I sent the mainboard back to the shop, but after testing they sent it back saying it works properly.
To sum it up:
- mainboard was tested again and seems to be fine.
- PSU powers on when bridging wires, so it should be fine as well?
- CPU is totally new and there is no visible damage.
Any idea what I should try now?
I would also be very thankful to get a few informations on how the Z87 Pro4 mainboard should react:
- if there is no RAM (I expect some beeping sounds - but the manual does not have any information on this. Does anyone know the peep codes for this board? Also, will there be any output on the screen?)
- if there is no CPU (Is it safe to power on the board without CPU? Will there be any beeps/feedback at all?)
Thanks in advance!
