    @zbook Looking at the error record for the hardware failure is a very useful step. The Machine Check Exception reveals why the CPU triggers the crash. In this case it was because of too much delay in the BUS.

    Let's wait and see what answers the OP gives to your questions on overclocking etc. Stress testing the system would be a good next step.

    Thank you so much for your support, guys.

    About BIOS settings and overclocking, I don't overclock this system (in fact, it's a laptop, so overclock isn't really possible without killing the MoBo, too much heat) and I haven't changed any settings in the BIOS (It's so mutilated that entering there is a waste of time... nothing to do there. Also. I don't think I'm doing any hardware Raid in here... I?m not sure what does that means anyway (at least for harware, I know about disk raid setups, but this is a laptop still, so, only one physical disk available) The only thing related to an "overclocking" is AMD Turbo CORE, which makes the processor get up to 3.4 Ghz (instead of the max 2.5 Ghz stock) But that is a default design... (I believe) and again, because of all the missing options in BIOS, I cannot disable that to test if that is the problem...

    I have made some tests in the past (when I was using build 1511) stressing the GPU and CPU, using AIDA64 and GPU-Z and Prime95... but not even a single crash, no BSODs, nothing... it's supposed a hardware failure might arise during those tests... but nothing happened. Windows updated itself this weekend tho, I'm now in build 14393.1358, hope this doesn't alter things...

    I've tested the clean boot thing... the PC works barely faster than it normally does... startup is the same as well as shutdown (which is rather fast, like 20 secs or less until I reach the dsktop, I don't use hybrid boot, waste of HDD space XD) In general, tehre is no change at all using clean boot, the system works blazingly fast, as it does currently with only the AV software and KeyboardLEDs app enabled (only that is enabled... I hate having useless stuff sitting in memory, even if I have 16 gig of RAM)

    About Updating the BIOS, that is a step I cannot do, because latest revisions have the RAM crippled (They cut your RAM from 15.5 GB to 7.5 GB...) I ignore if they have aditional problems so, I avoid upgrading it...

    I can try running the stress tests again this weekend, with the programs you sugest, and running memtest... unfortunately, I need to get job done here so, until then, I cannot run extensive tests

    The analysys you do, @philc43 is the same (or almost the same) you said about an intel processor you were analysing as well in other thread... weird question, could this be because of faulty drivers? I hope it is, because, if it's hardware, that means I have to RMA this thing once again, and this time, getting a whole new system...

    Thank you so much for your help, I'll try to get back at you this weekend, when I do all the tests.

    Yes, the CPU is triggering and reporting the reason for the crash but this does not mean that it is the CPU which is the problem. Overclocking is a common reason as is overheating, drivers sending bad instructions, motherboard failure, etc. There is great difficulty in analysing x124 WHEA BSOD events because the real cause is rarely revealed. Troubleshooting is a matter of trial and error and gradually eliminating possible causes. If the problem never happens in safe mode that can be a good indicator that the problem is not a hardware one.

    By Safe Mode you mean clean boot or are different things?
    And... is normal that there can pass months without a crash, and still be a hardware issue?

    Safe mode: Boot into Safe Mode on Windows 10

    Going for months without a crash does tend to rule out hardware unless you have some sort of intermittent connection or a seasonal effect such as high temperatures.

    Well... hopefully, temperatures aren't my issue, under full load, the system never passes 70 C... and well, that is the worst case, normally, this thing never goes beyond 65 C, and in idle, it reaches 30 C, or even 28 C... more funny is that, this crash only happened using Firefox, and just innocently scrolling a page... Never under heavy loads, which are supposed to trigger hardware issues... I even have run some GameCube games on emulators, and the PC never crashes... The most funny part is that I'm in the middle of the summer heat this season... I've been monitoring my temps since I bought this PC (I'm obsessive XD), and all goes normal in that regard... aparently.

    So, taking your word, then I must assume my problem is not hardware related, which is a relief, because, for example, this crash happened just a month ago after I reseted Windows (had to do it because there was a problem with Cortana not being enabled in my language, and a reset fixed that, not even the reg fixes XD) In fact, is the first time I reset windows, ver 1511 had no issues so far, but had this crashes... very seldom too, but became more rare when I updated the chipset and VGA drivers...

    I'm attaching the SMART info abut my disk... although it continues as healthy as I remember, I also include AIDA64 reports, in case those help in something...

    AIDA64 Full Report

    I'll do the memtest thing on the weekend, as promised.

    Let's hope is not a hardware issue, I can live with this until a driver fix is released in case is just that... maybe this has todo with the fact that this technology is still relatively new? Ahhh... XD

    I'm so sorry, just a heads up, I coudn't run the tests this weekend, I will try to find some time this days to do it.

    Sorry for not being active. After some analysis and usage, I narrowed my reboot problems to either Avast or Firefox, since this only, and only happens when I'm using that browser and scrolling a page. Never on Chrome, never Edge or IE11...

    Now, I suspect about Avast too because I had a similar problem when I upgraded version 17.2 to 17.5 and Virtual Machines started to trigger a reboot, but without a WEAH error... downgrading to 17.2 solved that, but still the problem with Firefox persists...

    So, by one hand, seems my problems are related to software rather than hardware (and drivers seem to work just fine) and just with an specific combination...

    I'll post updates as soon as I do something, my next step is to try replacing Avast with Panda Free and see if the problems stop...

    Wish me luck XD. (or if you have a good reccomendation for an AV that is lightweight and not complicated, I'm open to suggestions)

    Cya!

    Welcome back.
    It's been a couple of months.
    See if you can post some logs so we can troubleshoot them.

    Will it be OK if I post only the dump files? (unless the whole thing about running the utility for info gathering is necesary again) Sorry, is just that the last time was a pain to switch back to spanish (I don't mind english, but Cortana was acting up XD)
