Steps

Symptomes

1. Random restart sans BSOD
2. Artifact on the screen (lines, square, piece of window, etc.)
3. Error nvlddmkm (153)
4. Critail Kernel Power (41)
5. BSOD VIDEO_SCHEDULER_INTERNAL_ERROR
6. watchdog.sys
7. dxgkml.sys

Understanding the origin of BSODs

1. Event Viewer -> Windows Logs -> System -> Critical

WHAE erros

1. Install HWInfo and have a look at the bottom of sensors window

Read Minidumps

1. C:\Windows\Minidump
2. C:\Windows\LiveKernelReports\WATCHDOG
3. > You can use "WhoCrashed" and "BlueScreenView" to find out the origin of BSODs

Windows check

1. Runs SFC, DISM and CHKDSK commands to verify or restore Operating System files

3. /!\ I advise you to comment out the part "wmic recoveryos set autoreboot = false", because it is good that the PC restarts by itself (you save time and it is better than Force Restarting it)
4. Do a CPU, RAM and PSU stability tests with OCCT
5. https://www.ocbase.com/download
6. Désactiver les sécurités OCT sur les rails de votre PSU
7. Vérifier que la puissance délivrer par votre PSU soit bonne (3V, 5V et 12V) dans HWInfo (ou logiciel comme CAM)

Windows tests

1. Cancel all Overclocking you can do with software, BIOS, etc.
2. Do WIN+CTRL+SHIT+B to reset your GPU
3. Do all Windows Update
4. Update all yours Drivers (from Windows Update if you are in 11, or use Driver Booster or other)
5. Update your motherboard
6. Checked for virus and malware with Kaspersky or other
7. https://www.kaspersky.fr/downloads/free-antivirus
8. Disable from auto start Armory Crate, Razer Synapse, and all other useless
9. If you can, test on a fresh Windows install on a other disk
10. Use DDU in safe mode (hold shift when restart) to remove Graphic drivers, then install lastest version

Hardware check

1. Clean the dust
2. Check that everything is connected properly
3. If you're using a riser to vertically mount your GPU, make sure its PCIe version matches that of your CPU and GPU; otherwise, remove it
4. If you're using extension cables for your PSU, make sure they aren't modded cables, otherwise, remove them

Hardware tests

1. If you have, change your CPU thermal pad
2. If you have, change your CPU
3. If you have, change your GPU
4. If you have, change your PSU
5. If you have, change your RAM

Warning

1. Do not attempt to use 1st generation compatible cables with 2nd generation PSUs or vice-versa
2. Do not attempt to use 1st generation rizer cables with 2nd generation GPUs
