Windows 10: PC won't wake from overnight sleep. Need help with WhoCrashed outputs

Starting on January 10, my PC would no longer wake from overnight sleep. If it went to sleep during the day for just an hour or two, I could awaken it just fine. But if it slept overnight, it would freeze upon awakening, with a blank screen and nonresponsive to keyboard and mouse.
I have Windows 10 Home version 1903.
WhoCrashed analyzed the dumps and for each of these crashes, it found the same thing:

"On Fri 17-Jan-20 3:23:15 AM GMT your computer crashed or a problem was reported
crash dump file: C:\WINDOWS\Minidump\011720-99171-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x1C14E0)
Bugcheck code: 0x9F (0x3, 0xFFFF998AAD054060, 0xFFFF870F1D0DF8B0, 0xFFFF998AC14D3B10)
Error: DRIVER_POWER_STATE_FAILURE
file path: C:\WINDOWS\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This bug check indicates that the driver is in an inconsistent or invalid power state. A device object has been blocking an IRP for too long a time.
This is likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time. "

That's just one of many. Note that the time indicated (3:15 AM GMT) is when the computer went to sleep. So evidently there is a problem when the computer goes to sleep that prevents it from waking up the next morning.


I also ran WinDBG to try to isolate the cause, and it said this:

1: kd> !analyze -v

Arg3: ffff958f612298b0, nt!TRIAGE_9F_POWER on Win7 and higher, otherwise the Functional Device Object of the stack
Arg4: ffffcf001baf9010, The blocked IRP

Can anyone help me figure out what's going on here?

Sleep Mode... It won't wake up!

Vista wont wake up from sleep mode

my problem was first I couldnt get Vista to sleep - then I clicked start, sleep and off it went - now it wont wake up despite me pressing any key or shaking the mouse vigourously.

Has it had so long without sleep it is down for 14 hours like when I have a mad night out hee hee. Seriously - can somebody help please???? I have only had the PC for a few weeks so its brand new factory settings. I tried the power management thing first and it is set for 20 minutes if that helps. So its not the Vista settings thats the problem. I have two PCs in my house. I am on my Windows Xp machine now which wakes up easily with a little shake of the mouse. but the other is still asleep zzzzzz *Cry :cry:
