1. Disable Fast Startup

Fast Startup is a hybrid of the cold boot and hibernate options. In Fast Startup, the kernel session is not closed; it’s hibernated. The Fast Startup option helps to start your PC faster after shutdown, but sometimes it can trigger this error. Here’s how you can disable it.

1. Head to the Control Panel > Power Options and click on Choose what the power button does.

2. In the next screen, select the option Change Settings that are currently unavailable.

3. Now uncheck the Turn on fast startup (recommended).

2. Update Device Drivers
