Hi, new build and i got it up and running no issues. Was tweeking the cpu in the bios after that i couldn't boot, even into bios.

Pc starts up, fans and lights ok.
Green boot light constant and
White vga light constant
After selfcheck.

Tried clearing cmos (battery out) shorting cmos clear pins
Reseated gpu, m.2, ram, and cpu, no change.
Tried the same with and without bios battery in, no change.
Updating bios through usb flash, no change.
Tested gpu in another system, test ok.
Removed m.2 and installed a ssd with windows preinstalled(which works) no change, tried clearing cmos again no change.
Tried all 4 ram modules in the allocated slot according to the manual "Dimm_A2"
No change.
Sent the motherboard and the cpu to the seller, and they tested those okay.
Reinstalled everything, tried to boot, but same issue..
Btw, screen doesnt recognise the pc either, and ive tested the cable.

Have i overlooked something? Anyone got some tips or tricks?

Motherboard asus 570 F
Cpu 5600x
Ram vengeance 4000mhz cl18
Storage m.2
Psu corsair 850w gold
Cpu cooler coolermaster 360rad
Gpu geforce 1070 6gb

Swap in a different, known good PSU.

Pull the motherboard again and verify you have inserted a standoff in the case only were there is a corresponding motherboard mounting hole. A common mistake by the less experienced and distracted pros alike is to insert one or more extra standoff in the case under the motherboard. Any extra standoff creates the potential for an electrical “short” in one or more circuits. The results range from "nothing" (everything works perfectly) to odd "intermittent” problems to "nothing" (as in nothing works at all :(). So, you might want to verify you only inserted a standoff where there is a corresponding motherboard mounting hole.

Hi,

I believe load line calibration was the trigger of the fault.

Do you trust Seller completely?


Version BIOS for AMD Zen 3 Ryzen 5000 series CPU ?
Hi,

Yes, they got a good reputation when it comes to these things. They factory reset the mb (some kind of hardware was required) and ran a bios update.Should be the last update. They tested them ok. Can try and run a bios flash with the latest update just in case

Hi,
good thinking. I will check for short beneath the mb. I've messured all the pins of the psu, and it seem to be okay, but il try a good old psu i got laying around somewhere.

any chance you have a connection knocked loose or the wiring is not in proper position on motherboard? motherboard and cpu are alright.

Was LoadLineCalibration (LLC) the only setting you changed? I really don't think so. One would change this only if OC or UC was in mind.
Come on, you must never hide anything from doctor :D (I'm not the doctor, we all are together). What exactly do you mean by tweaking the CPU?

Are you sure you flashed the BIOS with the correct way through USB drive? There is a whole procedure to do that right and not just putting the BIOS file into a USB and pressing a button.
The USB must be on FAT32, plugged on the right USB slot and the BIOS file must be under a specific name. ASUS is providing a tool for the BIOS renaming after downloading it. And the BIOS FlashBack function takes place when system is off, PSU on. It can be done with or without CPU/GPU/RAM/SSD installed. Only the 24-pin connected is a requirement everything else is optional.

And try to run the system with different PSU, maybe diff GPU and cable to the monitor.

Im sure, checked this everytime when dismantling and reinstalling the pc

Loadline calibration was the one change that triggered the issue, after save and reset. Cpu core ratio was set to around 46 if i remember and the cpu voltage to around 1.325, ram was set to the default xmp profile.

The bios update was attempted with a formated fat32 with the bios file renamed to the name provided by asus.

I powered down the system , inserted the flash drive into the allocated bios usb flash port, clicked the button and the led started blinking green, did so for about 5 minutes, then it turned constant. Left i there for half an hour just to be sure it was done. Nothing happened on my screen during this process. Following i did a system restart but, the problem was still there..


just tried with another psu, same issue

Got mb out now. Theres only spacers in the marked AM4 holes. They all line up with the holes on the motherboard, and theres no rivets, screws, cables or foreign objects shorting the motherboard gonna try run it out of the case

I think it should restart by itself after the process of flashing is finished (=light stop blinking) or power off. Can't remember... last time I used Flashback was like more than a year ago. But the first 6 months I had to use it a lot as no clear CMOS could do anything to bring it back from blackness...

Maybe you should try again? And maybe with different BIOS version(s).

If you manage to start it don't try to OC it again. Ask for advise in the forum here. There is a lot of experience here by many users. For instance, 1.325V constant voltage maybe a lot for 5000 series under static speed.

Take the mb and cpu back to the seller and tell them to TEST the board with a known working cpu and test your cpu in a known working mb. For them it will be a 15 minute operation.
One of the two isnt working properly and until you find out which of them it is your just running around in circles.

I mean, I guess it is stupid for me to say but I am trying. Did you refer to the manual for CMOS reset? I say this because motherboards handle it differently. So maybe you assumed it did, but you did the wrong way?

Got motherboard on my table right now, and im able to boot into windows. Must be some kinda short, defective wire/plug, component or such. Remounting and testing as i go.
Thank you for helping me out

Again, check your standoffs. Cases are designed to support 1000s of different motherboards so there almost always are more standoff mounting points than motherboard mounting holes.
