WHEA_UNCORRECTABLE_ERROR 124 but no bsod

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

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

TIA

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

This looks like the same hardware error again. The CPU is reporting a BUS error.

Component: AMD Northbridge
Error Source: Machine Check Exception
Error Type: HyperTransport Watchdog Timeout Error
Processor APIC ID: 0

If you have not been able to track down any driver issues then it could be a motherboard problem.

Is Fast Startup still OFF?

Woops.. I installed a few updates recently, and it didn't occur to me that fast startup might have been re-enabled. I've just turned it off again

That solves my BSOD problem, however I wanted to ask about the entries in my event log that look like this:


Event[371]:

There's quite a few of these, is this something to be worried about?

Thank you so much, i apologise for my mess up

The system time change is quite normal and is simply the Windows time server keeping your system time synchronised. Sometimes you will see an explanation like:
Change Reason: System time synchronized with the hardware clock.

Thank you so much, marked as solved!

Hi,
System time change normal well if it changes region to west coast would be normal seeing I live in central/ Canada it's a pain fortunately it doesn't happen all that much but updates will mess up the system clock region just to irritate one really :)
