STOP 0x0000009F
DRIVER_POWER_STATE_FAILURE
A driver got stuck while your PC was going to sleep, waking up, or shutting down. The system waited, the driver never answered, and Windows pulled the plug. Network, GPU and USB drivers are the usual suspects.
Likely causes, most common first
- A network (especially Wi-Fi) driver that mishandles sleep/resume
- A GPU driver stuck during a power transition
- USB or Thunderbolt dock drivers
- Outdated chipset / power-management drivers
How to fix it
1. Update power-related drivers easy
- Update the Wi-Fi/Ethernet driver from your PC maker's support page.
- Clean-install the newest GPU driver.
- Install the newest chipset driver (Intel/AMD) from your PC or motherboard maker.
- If you use a dock, update its firmware and drivers too.
2. Disable Fast Startup (common quick win) easy
- Press Start, type "Choose a power plan", open it.
- Click "Choose what the power buttons do" → "Change settings that are currently unavailable".
- Untick "Turn on fast startup" and save.
- This removes the half-sleep state where these hangs happen most.
3. Update or roll back the identified driver easy
- Update the driver named in the report from the vendor link in the driver card.
- If that driver was updated recently, roll it back instead via Device Manager.
The four parameters on the blue screen
Windows shows four hex numbers with this stop code. Here's what each means — our analyzer decodes them automatically from your dump file.
| Parameter 1 | Subtype of the failure (3 = a device blocked an IRP too long) |
| Parameter 2 | Meaning depends on subtype (often the device object) |
| Parameter 3 | Meaning depends on subtype |
| Parameter 4 | Meaning depends on subtype (often the blocked IRP) |
