Assistance with diagnostics. Computer crashes, shuts down, resets

Appears to be an XPS 15 9500 running Win 10 Pro based on info in first image.  Please confirm model number...

What version of BIOS is running? Assuming XPS 15 9500 is correct, latest BIOS is 1.23.1.

Error "Intel SST-OED" Event 19 seems to happen on XPS 15  9500, especially if you're using a  dock. If using a dock, have you tried disconnecting it?

And read this thread too.

Are you running this laptop on battery or with the charger connected? Do the same problems occur either way?

Hello Ron, thank you for reaching out,

2. What version of BIOS is running? Assuming XPS 15 9500 is correct, latest BIOS is 1.23.1.

Actually not. BIOS Version: 1.22.0 / ED. 1.1.3 and there is no update from Dell Updater software or any other. I will try to update from the link you've provided.

3. Error "Intel SST-OED" Event 19 seems to happen on XPS 15  9500, especially if you're using a  dock. If using a dock, have you tried disconnecting it?

I am not using a dock. I've alredy tried the mentioned solution with uninstalling Intel drivers and it didn't wrok

4. Are you running this laptop on battery or with the charger connected? Do the same problems occur either way?

Same problems occur . To boot "faster" it seems like when I press "D" and it goes trough the LCD test than it's more likely to boot into BIOS and from BIOS usually to the system. Other than this it can take hours of restarting and powering off. Today I got this blinking keyboard when trying to boot:

I've actually noticed that the BIOS is "loosing" time and date and also it either doesn't save the changes I make or restores previous settings if start-up is unsuccessful. Im not sure about this one but for example I've changed C-States or Disablaed the microphone and after reboot it was Enabled again

- I have updated BIOS to 1.23.1

- For some reason I have RAID enabled in BIOS and I've read that if you don't have more that one drive it's better to use AHCI but I have to install AHCI driver first. Where do I find one?

Have you looked at Battery health info in BIOS setup? ff PC is losing time/date and not holding changes, this may be a battery issue. I don't see a coin cell battery on the motherboard or any mention of it in the Service Manual. It's typically used to maintain BIOS settings including time/date, so this PC model probably uses the main lithium ion battery for that. So check battery health...

I'd also run all the BIST tests on the PC. Note error messages, if any...

Dell installs Windows set for RAID, even if you don't use RAID, so that's "normal".  Before you change  BIOS to AHCI, you must reconfigure Windows or you'll make the PC unbootable. So leave this alone for now. Let's see if BIST reports any hardware errors before doing anything to Windows.

BTW: If this PC is still under warranty, you should contact Dell Support. Have your Service Tag available (don't post it here).

Hello Ron,

Thank you for sticking with me  

There was battery issue (but no information in BIOS etc) and by the time I've made first post, the computer was without battery. I've already changed it to a new one yesterday. Date and time works fine. It was "pumped" from the heat.

Im not sure that I understand how to use BIST or everything is just fine. When I press M+(PowerButton) (computer is powered off-there is no such info in tutorial just mention it needs to be done before POST) the LCD start changing colors (I thought it was LCD test that starts when pressing D). Anyway the battery light didn't go orange. 

I think the main question now is how to "catch" the error when computer gets frozen. It was turned off/frozen tens of times and not a sign of error. In some tutorials it's being said that when computer freezes you can still make memory.dmp while pressing CapsLock and NumLock. I have no "NumLock". Is there other way to do this?

It seems to be a little bit better now since BIOS update but still at some point it just go black. I will try to do a stress test for GPU.

I did GPU stress test and everything was fine. But later on I started to look for CPU stress test and installed temperature monitoring first and when computer seemed like it's almost IDLE the temperature already reached critical levels few times. Not during the stress tests but inbetween. I also noticed that even the surface of the laptop at some point was very hot in marked place so after installing BIOS I switched the cooling options to "cool". In the old BIOS when computer didn't keep the changes it was going back to standard fan options. Seems like unnatural overheating of CPU but still I think these kind of errors should be "caught" and written somewhere.

the two screenshots were not taken at the same time but still the temperature reached 100 C few times without any spectacular workload.

For now pretty unfortunate conclusion is that this is very bad designed computer. For some reason Mac that is even thiner doesnt overheat at all. I found some solution here:

https://www.tenforums.com/tutorials/107967-add-remove-maximum-processor-state-power-options-windows.html

But it's absolutely not a great solution for computer (in my case) that I paid for almost 5000 USD. I think Dell should just send the money back, provide some service or real solutions or extend warranty.

Edit option here would be nice... 

Just 2 seconds after posting the last post computer went down, again lost the time and BIOS changes that I've made earlier.

As for CPU I've switched off the Intel Turbo Boost technology in BIOS, switched fan to the maximum cooling option (ultra performance) and in the Power Options I've made limit of 99% CPU usage (needed to add this option with reg) https://www.tenforums.com/tutorials/107967-add-remove-maximum-processor-state-power-options-windows.html

Seems like the marked overheated part on the previously posted photos is the South Bridge and not the CPU itself. So I started to look for any hardware conflicts and it seems like it points to Realtek Audio driver, HID Filter, Intel Integrated Sensor Solution Driver, thunderbolt,  Intel(R) Dynamic Platform and Thermal Framework Processor, Goodix fingerprint. Some of them might be connected to turned off microphone, webcam or fingerprint reader. The strange thing I've noticed is Feitian USB. Actually I have no idea what it is. I don't have and USB Feitian hardware that I've used. Its security related dongle. Any ideas? I turned it off for now (maybe it's some "virtual" device).

Im not good with BIST. I think I've menage to see the blinks but all of them were white:

1short white 1longer white

2short whites

4short whites

I did M+PWR

If I pick up the computer with my hand like below (left lower corner) it will freeze:

Wasn't aware this model had such overheating issues. The pic you posted says CPU cores are overheating, not the chipset.  You have an i9 CPU that's known for all the heat it puts out. Users in the thread you linked are having overheating issues with an i7, which should run cooler than i9. So probably not surprising if your PC crashes when 2 or more core temps are "critical". You need to keep cooling at max possible levels, and possibly lower max CPU speed to 95% too. Do you have the latest Intel Dynamic Tuning driver installed, which is supposed to help with heating issues?

Don't know why M+power button launches the LCD tests. The numbers in ( ) on each BIST test instructions page, to right of the colored battery LED, tell you how many blinks you should see on that button if there's a problem, eg for L-BIST, 2 amber followed by 8 white (2,8) would mean there's no power to the LCD panel.

PC freezing when you pick it up from lower left suggests possibility a circuit printed on the motherboard, keyboard or touchpad, and/or a wired connection flexes and breaks a circuit. It may be time to have a professional look at this system. I presume you're in Poland, based on the language in one of your pics, but don't know if Dell offers an Out-Of-Warranty Repair Service in Poland or elsewhere in EU, like they do in USA, so you may want to investigate that.

Don't know why you have Feitian Rockey4 drivers installed, unless that's the fingerprint reader. Have you run a full malware scan? Malwarebytes (free) would be a good tool.
