Bonjour,
Ma config = HP portable elitebook 8540w windows 10 pro mem 4 Go
Sans prévenir il se fige une seconde puis écran noir une seconde puis tout redevient normal.
Il me fait ça 3 à 4 fois par jour, ce n'est pas très méchant mais énervant.
De temps en temps disons une fois par jour il se gele puis écran noir puis un bruit de cric cric - comme quand on vide la corbeille-
Puis il reboote seul.
Et la c'est encore plus énervant.
Bonne journée à tous

Peux tu nous poster le rapport complet du logiciel Whocrashed ?

re, je ne connais pas

Welcome to WhoCrashed (HOME EDITION) v 7.06
--------------------------------------------------------------------------------
 
WhoCrashed is a comprehensible crash dump analyzer. It analyzes the system crashes of your computer or a remote computer on the network.
 
If your computer has displayed a blue (or black) screen of death or rebooted suddenly then your system may have crashed because of a malfunctioning device driver or because of a hardware failure. WhoCrashed will go to great lengths to help you find the root cause of the problem and a solution if available. It will analyze the crash dump files on your system or a system on the network with the single click of a button. In case the problem is caused by a malfunctioning driver, it will tell you what drivers are likely to be responsible for crashing your computer. In case of a hardware failure, it will tell you the most likely root cause and how to fix the problem.
 
When the analysis process is complete, WhoCrashed will write a report that offers suggestions on how to proceed in any situation, including internet links which will help you further troubleshoot any detected problems.
 
WhoCrashed will do great efforts to find out why your system crashed and what can be done to remedy the problem.

Crash dumps are enabled on your computer.  
 
Crash dump directories:  
C:\Windows
C:\Windows\Minidump
 
On Tue 29/08/2023 15:30:21 your computer crashed or a problem was reported
 
Crash dump file:  C:\Windows\Minidump\082923-14109-01.dmp (Minidump)  
Bugcheck code:  0x133(0x0, 0x501, 0x500, 0xFFFFF80773CFB320)  
Bugcheck name: DPC_WATCHDOG_VIOLATION  
Driver or module in which error occurred:  intelppm.sys (intelppm+0x138f)  
File path: C:\Windows\System32\drivers\intelppm.sys  
Description:  Processor Device Driver  
Product:  Microsoft® Windows® Operating System  
Company:  Microsoft Corporation  
Bug check description: The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL or above. This could be caused by either a non-responding driver or non-responding hardware. This bug check can also occur because of overheated CPUs (thermal issue).  
Analysis: This is likely caused by a hardware problem, but there is a possibility that this is caused by a misbehaving driver.
This bugcheck indicates that a timeout has occurred. This may be caused by a hardware failure such as a thermal issue or a bug in a driver for a hardware device.

The following dump file was found but appeared to be corrupt: C:\Windows\LiveKernelReports\WATCHDOG-20230805-1251.dmp
 
 
 
--------------------------------------------------------------------------------
Conclusion
--------------------------------------------------------------------------------
 
7 crash dumps have been found and analyzed. Only 6 are included in this report. If one or more dump files were found that could not be analyzed, it means they are corrupted. It's an emergency measure for the system to write out a crash dump file and because of this, it's not uncommon for this process to fail. Often, but not always, it points to a problem in the storage stack. For instance, if the disk that should write out the crash dump file has failed, there will be no crash dump file written out. It is suggested that you run CHKDSK on your system drive to check your drive for errors.  
A third party driver has been identified to be causing system crashes on your computer. It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:  
 
nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 341.74 , NVIDIA Corporation)
 
If no updates for these drivers are available, try searching with Google on the names of these drivers in combination with the errors that have been reported for these drivers. Include the brand and model name of your computer as well in the query. This often yields interesting results from discussions on the web by users who have been experiencing similar problems.
 
Read the suggestions displayed in the bugcheck analysis above.
 
Note that it's not always possible to state with certainty whether a reported driver is responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.  
The analysis process took 0:00:15 (h:mm:ss).  
 
 
 
 

Tout pointe logiquement vers un souci de drivers GPU ou un souci matériel au niveau de ta carte graphique.
Essaye dans un premier temps de réinstaller les derniers drivers nvidia.

je l'avait fait, j'ai les derniers pilotes
Est ce difficile de changer de carte graphique ?
Je ne vois rien concernant le changement sauf que ça a l'air d'être impossible car la carte est soudée.
Pauvre de moi !
