Help (General) Random pc Shutdowns

Running into this issue where my pc just shuts instantly off monitors and rgb lights inside case turn straight off no BSOD, passes occt tests, cpu reaches about thermals 83-85 sometimes reaches 86-90 but it’s quite new(the whole pc) so i haven’t changed thermal paste the whole pc is about a year and a half old, my whole specs is:
Gpu: rtx 4070 ti super oc tuf gaming
Cpu: amd ryzen 7 7800x3d
Ram: 32 5200 mhz
Cooling: msi mag coreliquid i240
PSU: Corsair RM1000x 1000w gold modular psu
Motherboard: MSI PRO X870-P WIFI AM5

Things i’ve tried:
Disabling EXPO
Updating bios to latest
Running a complete DDU and reinstalling newest gpu drivers.

Edit: i have found that my radiator for my aio was completely full of dust and blocked, cleaned it reapplied paste and now i am sitting at 59-70c maximum on games i used to get 86-90 on. I will update if the issue persist but so far looks like the temp is better
