While Windows is an incredibly stable OS, it does run into the occasional bug or glitch at times. Now generally, you’ll see an error code with some explanation about what’s going on, but that’s not always helpful.

In this article, we’re looking at the 0xc0000001 error code, its causes and any potential fixes that can solve this.

What causes the 0xc0000001 error code?

This is a boot-time error that can be caused by several issues, including but not limited to corrupt system files, damaged SAM or an issue with your RAM modules. Your PC may or may not boot in this situation.

Even if you can boot your PC, chances are you’ll run into a BSoD soon enough. Luckily enough, most causes for the issue are easy to fix, except, of course, the issue with your RAM modules, which is most likely going to mean a replacement.
