Gigabyte Z370 HD3P POST restart after VGA Led

[ksalgadoic]

I´m building a new PC with Gigabyte Z370 HD3P Motherboard, i7 8700k, 64 GB memory Corsair 2666 MHz, CPU Fan Dark Rock 3 Be quiet(all the components are new). When booting the motherboard turns on the status leds CPU-DRAM-VGA and then restarts and repeats the same cycle (CPU-DRAM-VGA and then restarts). The motherboard doesn't arrive to boot. Please help me!!!

Did you use the onboard iGPU? or a discrete GPU? What PSU did you have?

Thanks for your answer. I use the onboard GPU. PSU: antec EA-500D (500 W).

on the power supply power leads did you plug in the 8 pin cpu marked cables into the eps connector on the side of the mb?? on the mb look for a bios rev sticker make sure the rev of the mb is at a rev that it post your new cpu. if your unlucky you may have gotten some old stock mb.

Check the cpu socket to see there are any bent pin(s) or not?

Thank you for your reply. Yes I plugged the cables into the EPS connector. The MB rev is 1.0 and it can take the CPU i7 8700k (8th generation).

Yes, I just checked and it seems ok.

Then, clear the CMOS, remove all, 64GB RAM, boot the PC without any RAM to see what happens.

If it does the same, and remove the boot device too, and boot the PC again. If the PC will not boot, then I think the MB may have problem.

As you suggested I removed all RAM and try to boot. When booting the motherboard turns on the status leds CPU-DRAM several times and at the end the DRAM led remains on and sounds 5 beeps, and restarts and repeats the same cycle and then turns off.
I don’t have a boot device. The HD is totally clean, the PC won’t boot and I can’t arrive to the BIOS screen 🙁

5 beeps? According to the gigabyte site, your cpu has problem. https://ddr4motherboard.com/beepcodes/GIGABYTE-Z370-HD3P-REV.-1.0 because the cpu socket is fine.

Ay caramba! So the conclusion is that the i7 8700k is damaged?

Most of time the MB will be easy to die, cpu is not. but here your cpu has problem, you may go back the store you bought the PC to ask for test and replacement ( for either the cpu or MB ), if they have the in-home services. Or even go to local PC shop ask for help too.

I thank you very much for your help and your patience. I briefly comment on some background.

I'm trying to build the PC by myself. It is not a PC for games is for engineering processes. Currently I use a PC with i5 2500K processor with 16 GB that I built 3 or 4 years ago. This PC takes up to three days to perform some engineering processes that I am working on and I intend to build a faster one.

The components that I am using have been purchased from Amazon. The MB that I am trying to use is the third one. First I bought an ASUS Z370-A that showed the red CPU LED on and didn't boot. I found that it had some blended pins in the CPU socket.

I ordered the change and the second MB arrives to do a first boot but never a second (It showed a blue window with errors, never the same error) and also appeared blinking lines on the monitor being in the BIOS configuration. I took it to a local service and its conclusion was that they found a problem with the video controller of the MB, I asked for a refund and I bought the third MB that I am currently using (GIGABYTE).

What do you think? Do I need to change the CPU (could it be damaged by the blended pins of the first MB?) or should I try with a 4th motherboard? Thanks for your time.

i would do both to make sure your cpu wont kill the next new mb.

I had the exact same problem (CPU-DRAM-VGA leds and then restarts) and when I replaced my PSU the problem solved (I had 450W and I've changed to 630W).
