Hard crashing issues

Hi crystalgenesis!

The issue is related to a driver that's not responding properly during a power state transition. The error code, DRIVER_POWER_STATE_FAILURE (9f), usually happens when a device or its driver fails to complete a power operation, like going to sleep or waking up. Since you mentioned playing Helldivers 2 when the crash occurred, it's possible that the graphics driver or another device driver is causing the issue. You can try updating your drivers, especially your graphics card and power management drivers. If that doesn't help, you might need to check for any system updates or try performing a system restore to a point before the crashes started.

Hope it helps!
