Windows 10: Laptop randomly freezes to a black screen

I am writing to seek assistance regarding a persistent issue I am experiencing with my HP Envy laptop. For the past few weeks, my device has been randomly freezing and, just few seconds, it goes to a black screen.The freezing occurrences are often unpredictable and can happen while performing various tasks, such as browsing the internet, watching videos, or even during basic document editing. Each time the laptop freezes, I am unable to regain control, and I have to force a shutdown by pressing and holding the power button. After turning it back on, the problem temporarily resolves but eventua

Windows 10 freezes randomly

I had already tried turning off fast startup, to no avail.
Will look at the list you provided, thanks. Hard to do when computer freezes on the Windows loading screen though. *Biggrin

I had tried that as well... no result.

 

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?

 

Black Screen and Keyboard freezes randomly

Dear Customer Support,

I have endured with the black screen problem for 3 months and now my keyboard freezes randomly,
after Windows 10 update.

1. After the October update, the "restart" windows option always restart with a black screen. I have to press the power button twice to bring up the log in screen. If I do a "shut down" option and restart the PC the login screen is displayed without problem. Can anyone help me?
2. After the November update my keyboard freezes randomly. I have tried uninstalled the driver or enable keyboard filter and some other methods found in google but still the problem exist. I have to shut down and reboot to have the keyboard working again.
Very frustrating and not knowing how I can solve the problems. Please help.
Thank You
