PS3 Shut down it self HEN 3.2.2 HFW 4.90

[Laur3]

Hello! I have some problems with my ps3 super slim with HEN 3.2.2 ,and HFW 4.90.1
1.Sometimes shut down it self with no red light power.I start again and it work good 3-4 hours.Last time when it happened was when i tryed to open "File manager" aplication, or when i tryed to enable HEN.
2. PS3 remain stuck into a black screen when i try to open aplication like multiman or file manager.
Before i had another ps3 slim 3004b HEN with the same problems.
I tryed to reinstall HFW,HEN and all aplication,i tryed to format and rebuild data base but the problems persist

change the thermal paste mx-4 it is ok to use !! after 2-3 years that paste will dry up and cause random shut down .the first symptom is a loud fan after 4-5 min..also check your temperatures just to be sure

are you using official hen installed either from ps3xploit.me or my github?
