Error 777 is the dreaded Blue Screen of Death (BSoD), indicating a total system error where the computer completely crashes because it can no longer operate normally.
When this happens, Windows will immediately fix itself and restart. Most of the time, this is all that needs to be done. However, if the BSoD keeps happening, you have a serious problem.
What causes the Blue Screen of Death on Windows?
If you’ve used a Windows computer for any extended period of time, you’ve most likely run into the Blue Screen of Death. We also know that soul-crushing feeling of having your unsaved work wiped out.
But what causes it in the first place? Well, as it turns out, there are numerous culprits behind the BSoD; all of which are easily avoidable.
- Your computer is infected with a virus – Malware is the most common culprit behind the BSoD. Immediately download some antivirus software to clean your hard drive.
- Corrupt files are messing up your system – Even if you clear out malware, the damage it causes can linger. That’s why you should run an SFC scan to clear up the corruption.
- You changed or deleted files in the Registry Editor – The Registry Editor is a powerful Windows 11 that lets you manage system files, but messing them can cause various computer problems.
How can I fix this Blue Screen of Death error?
There are several things that you can do to fix the BSoD, assuming that it keeps happening regularly. This is not an extensive list, but it should give you a good launching point.
- Run some antivirus software to get rid of the infecting malware, then restart your computer. After that, you should be good to go. MalwareBytes and SUPERAntiSpyware are good choices.
- To prevent getting infected with malware, be sure to install an adblocker to your browser to stop those annoying popups. They are a common vector for viruses.
- Make sure your computer stays up to date with its updates. Microsoft frequently rolls out fixes and updates to ensure devices are protected against bad actors.
- Also, be more mindful of what you click on the internet. Clicking random ad banners, popups, or hyperlinks can result in malware being installed without your knowledge.
- And if all else fails, reinstall Windows 11. This is a last-ditch effort to fix the problem by performing a clean installation to restore the default Windows settings.
1. Download the latest hardware drivers
- Go to the website of your computer’s manufacturer. In this example, it’s Dell.
- Identify your PC using the manufacturer’s on-page tools.
- Select the Check for Updates button, if there’s one available.
- After checking, download and install the drivers. Reboot your computer when done to finish the process.
2. Perform an automatic repair

- Give Windows 11 ample time to finish its process. Once done, sign into your account.
- Startup Repair will begin fixing the problem. Once done, restart your computer.
A bootable USB drive must come with Windows 11 ISO on it. If you don’t have this, be sure to check out our guide on how to create the ISO.
3. Reboot into Safe Mode with Networking
