Seemingly random black screen after sleep and keyboard disabled

Hi,

When I send my desktop pc to sleep, it sometimes comes back, sometimes does not. When I say he doesn’t come back I mean he restarts, it just doesn’t show anything on screen: only a black screen. I can’t seem to establish a pattern of when it happens beyond that it usually happens the third or fourth time I send it to sleep (the trigger might be time of sleeping frequency). Running Windows 10 home, 1909, 18363.657.

I’ve tried this troubleshooting by now, to no avail:

1. Turn off Hibernation: “powercfg /h off” on Command Prompt (just tried, even if the pc is a desktop)
2. Turn off Fast Startup: I think I did this, though can’t seem to find the setting any more on “Power Options/Choose what the power button does/Change settings that are currently unavailable” (been fighting this problem for some weeks now). I may have dreamt I turned it off : S
3. Disable “Wake on Magic Packet” and “Wake on Pattern Match” on ‘Network and Sharing Center/Change adapter settings/Properties (of the connection without the red cross)/Configure’.
4. “Windows key + Ctrl + Shift + B”: I would swear it once worked (maybe the pc was just slow waking up). I’d gladly try it out again, if not for the keyboard being lately disabled by the event of black screen. I’ll elaborate:

I’ve usually woken up the pc by pressing a keyboard key (also in the previous W7), and so I do now. However, now, when the pc is slumbering, I wake it up pressing a key, and the black screen case happens, the keyboard doesn’t seem to work anymore: lights off, and no living signals.

Maybe it has something to do, maybe not, just to let you know: I’ve always had problems accessing BIOS through this very keyboard (the one figuring in my pc specs), as it has never (neither when running W7) seem to turn on before Windows was initiated. In those cases I just used an old keyboard which works through a PS/2 port. Yet, I can’t see why these cases should be related, as in the matter in hands Windows is already launched.

Thank you in advance

The first step is to check all your drivers are up to date and run sfc /scannow from an admin command prompt

Hi,

Thank you for your replies.

- I’m afraid I don’t know how to check whether all my drivers are up to date. I read Windows 10 also updates drivers. If it’s not doing it, do I have to update one by one in the Device manager? Is there any way to tell Windows to update them all simultaneously? Or will I need to download a program that manages it?

- I’ve recently sfc /scannow quite a lot. Once again, it tells me: “did not find any integrity violations”

- Serial Number (if that’s what you mean): 3122300007
- Motherboard Model:
Manufacturer: Gigabyte Technology Co., Ltd.
Product: EX58-UD5
Serial Number: blank
Version: x.x

I get Windows 10 cannot identify all the hardware information. Should I install software able to do it, or will it be better (if possible) to open the pc and physically check it?

- I do not know if my BIOS is up to date. I doubt it. I’ll check it. I’ll also check video driver, which I also doubt to be up to date, though neither of these things game me problems before W10 : /
(the pc’s 10 years old, but fit as a fiddle (almost)).

New information:

- I am definitely unable establish a pattern concerning the “black screen after a nap” happening: it seems very random.

- I didn’t even imagine it could be related but, speaking about drivers, I’ve been having a driver issue for some time now:
Some years ago, I had some driver problems, and resorted to the Device manager, using the “Uninstall/Hope to be automatically installed again” trick I’ve seen on the internet. I had already used this method successfully in the past. I did fix what I needed (cannot remember what it was), but it seems I screwed something up as, since that day – even after going from W7 to W10 – I’ve been being insistently informed by windows that a USB port is not recognized.
Also, in the Device manager, one of the USBs says: “Unknown USB Device (Device Descriptor Request Failed)"

Back then, I didn’t give it much importance, since everything continued working fine. Can this have something to do with the keyboard? (the keyboard I’m typing with, but the one which dies after waking up the pc from a sleep (had never done that before W10 (only typically failed and fails to work before Windows gets started))).

EDIT.: By the way, I've already tried the "Uninstall/Hope to be automatically installed again" trick with the failing USB.
