The PC is unable to completely enter sleep mode.
The PC is unable to completely enter sleep mode.
I found two other posts that were never resolved, and I've shared my experiences elsewhere without getting much feedback. I really wish someone here could help me understand what's happening.
I'm not sure if the issue is hardware-related, since I've been gradually upgrading components.
Since the problem began, I've replaced the i5 4590 with the i7 4790 and switched to an EVGA 650w GQ 80 Plus power supply. But after moving the GPU from a 750 ti to a 1070 ti, I needed an extra 8-pin connector from the PSU. I discovered the PSU was defective and the PC would shut down unexpectedly during gaming without a BSOD. (I tested this with several 1070s to rule out the PSU.)
After these changes, I can no longer put the PC to sleep. The monitors turn off, the HDD slows down, and the keyboard/mouse shut down. But the PC power indicator stays on, while the fans spin and the drive activity light flickers.
Eventually, after about five minutes, the HDD spins again and the PC powers off completely. I've also experienced a case where my main monitor wouldn't turn on after sleep from inactivity—until I pressed the power button off and then turned it on.
I've tried disabling Hibernate, Fast Boot, resetting power settings, doing a clean boot, installing Windows 10 Repair, and replacing the RAM. Nothing worked. The only solution seems to be putting the PC to sleep right after turning it on.
Recently, I also encountered a TPM Module Failure Event in the Event Viewer after forgetting to reset power management, which caused the PC to fail to auto-sleep.
I'm not sure if this is connected, but I haven't had any problems with stress tests for GPU, PSU, or CPU. The main issue is just being unable to sleep.
Did you verify the functionality immediately after a clean boot?
What method did you use to configure a clean boot? MSConfig?
Were all non-MS Services also turned off during that process?
In short, there is likely something running in the background that prevents the system from sleeping. It could be a random service, a system process, or another program. It might be necessary to perform a clean reinstall and carefully review each step during installation to identify the cause, though that is a more extreme approach. There are techniques for achieving a genuine clean boot to help pinpoint the issue before taking that step.
The clean boot I carried out wasn't part of this guide, yet I followed identical procedures. In the end, I disabled all non-MS services as well.

Initially, the clean boot appeared effective—I tested putting my PC to sleep multiple times throughout the day, even after using it for hours gaming, working, and browsing. Yet unexpectedly, the problem reappeared without reactivating any of my regular applications.
After that, I simply turned everything back on since the issue persisted. At first, I suspected my Bluetooth Adapter was the culprit. The PC would sleep normally until I connected the dongle, and even my spouse’s dongle worked similarly. I’d also observed that occasionally using the dongle caused my mouse to lag and strange beeps when opening programs like File Explorer, which stopped once the dongle was removed. However, this now happened even without the dongle.
I’m currently stuck. I could attempt a complete reinstall, but I’ve been careful about that. It might be my only remaining choice.
