Hi Axel,
BugcheckCode 313 usually means 0x139 KERNEL_SECURITY_CHECK_FAILURE.
Your dump shows:
CORRUPT_LIST_ENTRY_KTIMER_LIST_CORRUPTION
This usually does not mean ntkrnlmp.exe is the real cause. It more often points to a driver corrupting memory before the crash.
Since SFC already repaired files, please restart and monitor first. If it happens again, please provide your PC/laptop model or motherboard model, and I can help you find the correct chipset, GPU, network and storage drivers.
Also, temporarily disable any overclock/XMP or hardware monitoring/RGB tools for testing.
If another BSOD happens, please upload the new minidump file as well, so we can compare it with this one.
