Question System won't restart or resume from sleep ?

[acirulis]

Specs:
Mobo: ASUS Prime Z790-A (new)
CPU: i7-13700K (new)
RAM: 2x16 DDR5-6000 (G.Skill F5-6000J3636F16GX2-TZ5K) in A2, B2 slots
PSU: 700W Thermaltake

Cold start works perfect, fast, Windows launches, no crashes.
Q-LED sequence: Red -> Yellow -> White -> Green -> POST + BOOT

However, normal restart or resume from sleep won't work.
Q-LED sequence: Red -> Yellow for longer period -> All led OFF -> Nothing happens.

Also exit from BIOS will result in same behavior - no POST.

Only solution is to do cold restart (with physical button) or turn power supply off/on. After that - works like a charm.


I have wasted several days troubleshooting this issue:

• updated BIOS & IME firmware to latest
• reset CMOS
• Experimented with XME settings
• Reinstalled Windows on different NVMe drive on different slot. (however, as stated it is not an OS issue, because exit/restart from BIOS also fails)
• reseated RAM, tried 1 and 2 modules.
• reconnected all the cables.
• removed video card (using internal gpu)
• Updated firmware for NVMe

I have found similar issues around a lot without working solution. Maybe somebody has any ideas before submitting to warranty.

UPDATE: Specified Q-LED sequence, updated NVMe firmware.

check HDD/SSD with the manufacturer´s software and eventually update the firmware of these

replace the power supply

Thanks. NVMe firmware updated & tested. Same results.
Actually - storage can be removed, same issue remains with exit from BIOS - no POST until cold restart.

I will try to get my hands on other power supply but really doubt it will help (power supply is few years old and have been working great. 700W is also enough)

In original post, I added info on Q-LED sequence in cold boot & restart scenarios.

Also tried re-seating CPU as per https://forums.tomshardware.com/thr...er-sleep-restart-or-normal-shut-down.3770025/

Power supply replaced with Be Quiet! 750W, including 2x 8-pin CPU connectors (previously only one was available). No change - after restart, blank screen, no POST.

UPDATE: So new BIOS version (1205) came out today - only 5 days after last one, so - oh, they may have found a bug. Also corresponding ME firmware (16.1.27.2176v2_S) was out.

So I installed ME first - and when it forced the restart, computer booted fine for one single time. BIOS update did not help.

However, now I`ve discovered new symptom - every time I install same ME firmware (utility does not check if same version is already installed), reboot works fine! But next reboot from either OS or BIOS fails again. So I am thinking that it is actually firmware fault, not hardware.

Is this problem from new, or it just happened recently?
If I ware you, would install Windows from fresh, if it's at all possible.

I have already stated that I reinstalled Windows, on different NVMe drive, on different M.2 slot, without changes. Also problem occurs by simply exiting from BIOS, so it is not an storage/OS issue. It is a new build.

In that case, I would think a hardware fault. Most probably the motherboard.

I am not so sure after latest find - every time I install latest ME firmware (utility does not check if same version is already installed), reboot works fine! (while any other scenario - OS restart, exit from bios - still fails)

hey, any update? got exactly same issue and im thinking about sending back motherboard.
(b760 gigabyte, i5 13600k, new build.)

Hi, yes, SOLVED.

It turned out that CPU socket had few bent pins (https://prnt.sc/jcBk5FZsRFE1) - local service found them.
Not sure, did it come from ASUS or I somehow managed to damage them on first assembly.

ASUS refused to replace it on warranty (ok, maybe fair) and support was one of the worst I have encountered - for example, they suggested that RAM is not on the QVL list until I sent a screenshot from their own website.

Local service guys also warned that ASUS over recent years are having many problems with ram compatibility, bios stability, etc.

End result - bought a similar MSI motherboard, build quality and overall experience seems much better.

I'm glad you found a solution.

I have a similar experience with gigabyte support, they suggest that every other part of my computer may be broken but not the board.

checked my socket but it looks fine.

I think I'll just send the motherboard back because it doesn't let me sleep at night. Regards.
