The suggestions from and are useful starting points. The problem that makes a PC reboot before Windows appears is often at the kernel or hardware level, so the next steps should capture any crash details and run low-level diagnostics rather than only reverting settings.

Collect and read the crash data before wiping anything. Disable automatic restart so any stop code or blue-screen text stays on screen. Minidumps live in C:\Windows\Minidump (when present); instructions for analyzing dumps are at .

Repair system integrity and files from recovery or Safe Mode with an elevated prompt: run sfc /scannow and chkdsk /r to repair system files and the disk. Official command references are here: SFC and CHKDSK.

Stress drivers and test RAM and storage. Driver Verifier can expose a bad driver that only fails under load (). Use a dedicated RAM tester such as MemTest86 (MemTest86) and vendor disk tools (for example, SeaTools for Seagate drives) to rule out hardware faults.

If the system never shows a stop code and reboots instantly, suspect power supply, overheating, or a faulty board/component; try a minimal hardware configuration (one stick of RAM, no extra drives or peripherals) and check temperatures and PSU voltages. If diagnostics are inconclusive, boot from Windows install media to run Startup Repair or to back up data before attempting an in-place repair or reinstall.

When you boot into safe mode, try running a system restore to a point in time before this started happening.

as it boots up., press F8 continously until it comes up with an advanced versio of the "would you like to boot to safe mode" screen. look for the one that says "load last known good configuration", and try that first.
