What are Blue Screen Errors and What Causes Netio.sys?

Blue Screen Error

Problems with your computer’s hardware are the most common cause of blue screens. There are also problems with the hardware updated driver software. Issues with low-level applications operating in the Windows kernel can sometimes cause them. Apps that aren’t designed to create blue screens are unlikely to do so. When an app crashes, it does so without crashing the operating system.

When Windows meets a “STOP Error,” a blue screen appears. Windows will crash and stop running as a result of this severe failure. At that moment, the only thing Windows can do is restart the computer. Because programs don’t have a chance to store their open data, this can result in data loss.

Windows creates a “minidump” file that contains system crash information and saves it on your hard drive when you see a blue screen. You can look up information on these minidumps to know if you can figure out what’s causing the blue screen.
