Random Hard Reboots

[ShiBDiB]

I'm fairly sure my mobo is kicking the bucket but wanted to get some second opinions before I buy a new one.

PC will hard reboot, no minidump generated and no bsod. It occurs at random, has happened in games and while sitting at the desktop. Has even happened while sitting in the BIOS.

I've also had issues getting the PC to wake up from sleep/hibernate which might be unrelated.

Steps I've taken,

- Got a new PSU
- Got new RAM
- Fresh windows install
- Made sure drivers were good
- Updated mobo bios
- Disabled DOCP and any other non-stock bios settings

So all that (the crashing while in the bios especially) seems to point to my mobo failing. If anyone thinks otherwise please let me know before I pull the trigger on a new one.

I would say it is a bad power supply, but you already took care of that. Flakey soft-off case power button? Have you tried disconnecting the front case buttons from the motherboard to illiminate switch or wiring issues? Otherwise, it must be the motherboard, huh?
Edit: assuming you have verified you don't have a power strip or outlet issue.

Fresh cmos battery as well, tried a different gpu?

I would take your board out of the case and make sure nothing got on the backside of it

I was thinking about trying a fresh CMOS but haven't seen any timeloss or anything in the BIOS while it was completely turned off (psu off) overnight. GPU I'll have to go dig in the garage for something to test with, but I'd figure we'd see a bsod or different issues if the GPU was the culprit.

It's annoying because I can go a day or 2 with no issues, then days like today it'll be completely unreliable and I've had it hard reset 4 or 5 times.

I'm usually pretty good at troubleshooting and everything to me is pointing to the mobo being the issue.

Have tried 2 different outlets with 2 different power strips (same breaker tho, although the pc is the only heavy load thing on it). Unless the circuit has suddenly become unreliable out of the blue I think I can rule that out. The power switch idea would be a weird one, I can try with those unplugged for a bit.

Just trying to exhaust the solutions, sometimes it's other parts installed, cr2032 battery is worth a shot even.

I typically would disconnect external devices like usb even.

It would be disappointing if your mobo is toast.

Ya not thrilled about spending money on an AM4 board, but also not in the mood to drop the ~700 to get an AM5 running lol.

The 5800 oem build i did in 2021 uses an AsRock Steel Legend B550 motherboard, still going strong, its not mine and at somepoint I need to be called in to do some dusting of it lol

So I would suggest to try Linux and see if the same problem happens. Also, do you have a UPS ? A spontaneous hard reboot has to be either triggered by something or be due to power loss. You can try one of Kubuntu images that installs from USB stick - you can do a trial run without installing anything. Assuming everything boots fine, you can see kernel messages open a terminal ("konsole") and type "dmesg". If you don't have a UPS, go into the BIOS and make sure the action for recovery after power failure is to keep the computer off.

So had my first reboot where I could point at something and go "that caused that".

I have IEM's and a mic, but also have a Razer Leviathan soundbar for when I want to save my ear holes. Turning on the soundbar (which is connected to the PC via USB) resulted in an immediate hard reboot.

I'm now using the PC with that turned off (and DOCP and whatnot turned back on) to see what happens.

If this does end up being the issue, I don't think it's drivers related as that should get a minidump/bsod. So USB/Mobo still technically seems to be the culprit, but not to the point of needing to replace it.

EDIT: JK, just crashed again... So seems to be a symptom and not the problem.

UPDATE

I've replace the motherboard so, hopefully these issues disappear.

Final Update

New mobo is working smoothly. Little hitches I used to have that I chalked up to windows gremlins have also disappeared. So something was on the way out on the old mobo.

New mobo being the MSI MAG B550 TOMAHAWK which replaced the Asus TUF GAMING X570-PLUS. An upgrade to AM5 wasn't something I felt like stomaching financially at this point.

My experience as a tech as follows...

When AT&T had Uverse in 2013, I remember complaints of user's service losing sync, and it did the same to them on comcast.
This was a common problem on Sony TVs with set top boxes directly hooked up via coax/hpna to a splitter, hpna filter, to the modem.
Those TVs over HDMI would produce a stray foreign voltage which would backfeed to the STB which would affect the coax and to the modem causing the modem to lose sync.
The fix was to use component cables.

Hopefully your sound bar is not bad since it did trigger 1 of the hard resets.
