Windows 10: PC still on and running but black screens randomly

Okay so this has been happening after my PC updated a couple days ago and i cant figure out why. So my PC randomly black screens with my PC still running but becomes completely unresponsive. Power button doesn't work and neither does the keyboard or mouse, the only way i can get back on i have to switch off the power supply and reset. I updated everything but nothing seems to work.

I thought i might have been a heat problem with my CPU idling at around 50C but after running some games and looking at temps, it didn't go past 80 so I don't think its a heat problem.

Any help would be greatly appreciated.

New laptop hardlock with black screen

I have a new notebook, running Windows 10 Fall Creators Update, which is randomly freezing, showing a black screen. System specs:

• intel core i5
• HD is an SDD, 250GB
• GPU: Intel HD graphics 620

Symptoms:

• happens randomly, related to no particular reason, time of the day, and programs running
• when freezes, the notebook screen is "active" (back light is on) but completely black; external monitor, connected via HDMI, is black as well
• when freezes, no key input is responding. I tried to press "CAPS Lock", which has a led on it, and the led is not toggling
• I noticed I can keep the PC on for several days, without any problem. It always freezes whenever I'm actively using it

What I already tried:

• reinstall Windows from scratch (even starting from an external USB drive)
• run windows in "clean boot" mode (all non-MS services disabled, all startup programs disabled)
• update the BIOS, and all "relevant" drivers (GPU, System Firmware, network interface, bluetooth, ...) of the PC to the latest version
• testing the memory with MemTest86+: no issues, after several steps
• stressing the GPU with FurMark: reached quite an high temperature (70°), but no issues
• stressing the CPU with IntelBurnTest: reached quite an high temperature (70°), but no issues

Now, I would guess it's an hardware problem, but the strange thing is that we ordered 6 identical PCs, and this is happening on 4 of them. Therefore, for "statistical" reasons, we don't think it could be possible that all of them shows an HW issue... It only happens with a different rate from one PC to another (for instance, happens daily on my PC, and once a week on another)
Any idea on how to investigate this issue further?
Any test / improvement I can do?

 

Computer randomly has black screen and restarts

Taco this could be software also. Before you get all crazy, do as Erocker suggested. Find out the error in the Event Viewer. Look for the faulting module and the error code itself. Also check the reliability monitor. At the bottom it will have "View all Error Reports". Post a screen of whats in there if anything.

This could be a simple as a bad driver install.

ALSO have you downloaded or installed anything lately? STAY OUT OF THE DAMN BIOS UNTIL WE KNOW THE ERROR! lol. I know you. Baby steps boy, baby steps.
