fix windows crashes after sleep on PC

Sleep Mode is a handy feature in Windows that allows users to put their PCs in a low-power state with the programs and files running in the background, and things can be quickly resumed from here. But for many, Windows crashes after sleep.

While Windows crashing is nothing new, and we have all witnessed it at some point, a Windows 10 BSOD after waking from sleep indicates a major problem requiring immediate attention. So, let’s find out all about the problem and the most effective solutions.

Why does my PC crash after waking up from sleep? Here are a few reasons your computer crashes after sleep:

  • Misconfigured power settings: Certain power settings, when set incorrectly, both in Windows and the BIOS, have been found to lead to a BSOD when the computer goes to sleep.
  • Incompatible or outdated drivers: If the drivers are outdated or incompatible, Windows will find it difficult to load them after sleep, which might trigger a crash.
  • Running an older version of the BIOS: BIOS plays a vital role on the PC and needs to be regularly updated for an error-free experience.
  • Corrupt system files: Another reason often found responsible for computer crashes when hibernating or in sleep mode is corrupt system files.

What can I do if Windows crashes after sleep?

Before we move to the complex set of solutions, here are a few quick ones that worked for others:

  • Hold the power button to restart the Windows computer and verify whether it still crashes after sleep. If it’s a one-off thing, you are good to go.
  • Disconnect all non-critical external devices before putting the computer into sleep mode since these are often why the OS crashes.
  • If the PC is overclocked, revert to the default settings and uninstall the program used for overclocking.
  • Update the BIOS, and check whether Windows still crashes after sleep.
  • Make sure all the RAM modules are properly plugged in. Remove all, wipe them with a soft and clean cloth, and place them back in.
  • Disable VSync in the NVIDIA Control Panel.

If the problem persists, head to the solutions listed next.

  4. Once done, execute the following command to run the SFC scan: sfc /scannowsfc scan to fix windows crashes after sleep
  5. If the SFC scan identifies issues with a DLL file, either use a DLL repair tool or copy the same DLL from another computer to the affected PC and remove the existing one.

Corrupt, damaged, or missing system and DLL files can cause Windows crashes after sleep, but as we said before, the easiest way to approach this task is by using a DLL repair tool.

2. Uninstall the conflicting application

  2. Click on the ellipsis next to the problematic app, and choose Uninstall.uninstall app to fix windows crashes after sleep

5. Check for issues with the drive

6. Test the RAM

When faced with Windows crashes after sleep, you should also look for issues with the RAM. Since you have already cleaned and reinserted the modules as recommended earlier, it’s time to run a bunch of tests. First, go with the built-in Windows Memory Diagnostic tool.

If that doesn’t work, you can use Memtest86+, an open-source memory testing tool, to identify and eliminate issues with the RAM. You should run the tool overnight since it takes considerable time, given its deep scanning of individual modules.

7. Reinstall Windows

When nothing else works, the last option is to reinstall Windows. You must create a bootable Windows drive and then install the OS via it.

Remember, this will wipe the data stored on the drive. So, it’s recommended that you use a reliable backup tool to retrieve the files after reinstallation.
