Code: 0x00000124: [SPECIAL] WHEA_UNCORRECTABLE_ERROR (2018-02-19 14:36:04) [Windows 10] CAUSED BY: AuthenticAMD_PROCESSOR_BUS_PRV WHEA Notify: Machine Check Exception Type: BUS error Error: BUSLG_OBS_ERR_*_NOTIMEOUT_ERR (Proc 0 Bank 4) PROCESS: System[/quote]
"BUS OBS Error": Observing error. Usually caused by hardware components, Mainboard or chipset drivers.

 

Nothing new then... what I should do next?

 

Is replacing the mobo the only solution?

 

There is also the same error in the eventlog:

Code: 2018-02-19 13:38:19 Error: A fatal hardware error has occurred. Component: AMD Northbridge Event[2781]: Log Name: System Source: Microsoft-Windows-WHEA-Logger Date: 2018-02-19T13:38:19.089 Event ID: 20 Task: N/A Level: Error Opcode: Info Keyword: N/A User: S-1-5-19 User Name: NT AUTHORITY\LOCAL SERVICE Computer: DESKTOP-CMBIKBN Description: A fatal hardware error has occurred.

Seems to be an known error on you mainboard:

BSOD - GA-78LMT-USB3 causing it? - Motherboards - Toms Hardware

Amd NorthBridge Error type 11

 

So is there anything that could be causing it other than a faulty mobo? I've tried everything I can think of

 

Please post you PSU model

My psu is an Ace A-750BR, Thank you for the other links, I'll look at those

 

I forgot to mention, I had a couple of random restarts before the new BSOD occurred. I'm pretty desperate for help, if there's something wrong with my zip please let me know

 

I thought the issue was solved, but just had another crash. I didn't actually see a BSOD, I believe i have fast startup off so do you think there's any reason for that?

Before the crash, I was playing a game and I kept hearing the USB disconnect and then reconnect sound. I had about 9000 ping in game, until I heard the disconnect sound and then nothing. I noticed the lights on my USB wifi device were off, i tried unplugging and replugging but the only thing that got it to work was plugging it into the port my keyboard was plugged into. Upon plugging my keyboard into the USB port that caused the issue, it lit up but would not register any input.

So i stopped using that port, and tried to check Speccy to see if my temperatures were too high. While moving the speccy window onto my other monitor, the screen froze and there was a buzzing noise lasting about 5 seconds before it rebooted.

New ZIP attached. I checked the event log and saw a WHEA error - so I assume it is the same error and should be posted in the same thread? Please let me know what i should do next, I don't want to replace the motherboard *Sad

TIA
