If the blue screen error is originated from third-party tools or services, you will be able to access the PC without any error.

After booting into Safe mode, you can deploy workarounds that generally fix critical system errors such as virus scan, installing updates, uninstalling unnecessary apps, and more. Some of the resolutions might need internet access to carry out the process, hence, go for Safe mode with networking instead of a usual one.

1. Press – Windows key.
2. Type – advanced startup.
