Hi, my French is very poor, https://translate.google.com/ might be useful.
W10 is 1511 or 1607?
The STOP 0x000000EF: CRITICAL_PROCESS_DIED BSODs do not usually leave dumps, usually they cannot, I think because that would require the dead critical process.
Crashes during boot, like these are usually drivers/filters, often 3rd party 'utilities' that run close to the kernel, AV/3rd party defrag/motherboard/graphics utilities, etc. or incorrect/corrupt drivers 'updated' by Windows in the previous session (?chipset/graphics?). It could easily be malware, root/bootkit, etc. Hardware/memory is less likely but may be data corruption/page file corruption.
"Memory management" often refers to a 3rd party driver loading in the wrong memory space, causing corruption of the memory data that should already reside there (exact BSOD details, 0x0000000 (0x0000000, 0x0000000, 0x0000000) can tell us if it was a failure to read, failure to write, etc. - can be useful).
The clean install is a good suggestion, I would use a fresh download ISO, in case the original is 'bad'. Perhaps install offline, if you can, it could be an updated driver that causes the problem.
