Had a look through your dump files am having issues getting them to load properly as well
All dumps report error 0x9f DRIVER_POWER_STATE_FAILURE
BSOD Index
they all reference the kernel driver but this cannot be the case or you would have much bigger problems
Most of the dumps blame disk.sys as the faulting driver, may be worth running some HDD diagnostics to check the state of the drive

You also have some old drivers on your system that could do with updating or removing
