Quoting: Why a portable Linux install is my favorite troubleshooting tool —
That is where a Linux USB (or external SSD) helps. It can help rule out most hardware problems almost immediately.
For example, if your PC crashes while gaming, you could be experiencing a problem with Windows, a driver error, or a hardware fault related to literally any of your PC's components. If you've tried updating your graphics drivers (the most common fix for a crash while gaming), booting into Linux on a USB drive and running some intensive application will immediately tell you if you have a hardware problem or a software issue.
If the Linux USB crashes too, you almost certainly have a problem with your hardware, or potentially a BIOS issue. If the Linux USB runs without issue, you can be pretty sure that you have a software problem on Windows, usually with a driver or the operating system itself. You've instantly cut the number of potential problems you have to explore in half—or more.
