Hello Phederico,
Thank you for posting on the HP Forums!
I understand the computer is experiencing a service exception BSOD stop error. Usually this is a hardware related error, but I will do what I can to assist you! To troubleshoot, please try the steps in this Microsoft document: How to fix Stop errors on a blue screen that cause Windows Vista to shut down or restart unexpectedly
I believe these steps will be able to resolve the issue. If not, this would indicate that the hardware is faulty. Unfortunately, the computer would need to be serviced at this point.
Please let me know if you have any other questions. Thanks again for posting on the HP Forums. Have a great day!
Mario
