Types of BSODs

There are various types of BSODs, each of which requires different actions. While installing a new version of Windows — the de facto fix for BSODs — will often work, they will also require users lose valuable data if not backed up.

These are the top-level reasons for a BSOD:

  • Driver Conflicts — Driver conflicts occur when two or more drivers (software meant to use and control hardware) cannot work with one another properly. This can also occur when multiple drivers are installed for the same device without uninstalling a previous version.
  • Hardware Conflicts — Hardware tweaks can lead to BSODs. Unsafely overclocking a PC, for example, can immediately create a BSOD. However, BSODs can also occur if your RAM sticks are improperly placed or if a piece of hardware is beginning to fail.
  • Operating System (OS) Errors — From time to time, user error or malware can chip away at the vital files of your OS. This can also occur when using an Insider Preview of Windows. Crucial missing files may lead to a detrimental error, causing your PC to enter a BSOD loop wherein you receive a blue screen every time your computer turns on.

While there are only a few reasons for a BSOD, your particular issue may still take a while to diagnose. The following will allow you to identify the culprit.
