Question PC crashes after gaming for some time

[respeccbanana]

Hey there,

For some background, recently I've upgraded my PC parts (CPU, MBO, RAM). The parts in question are Ryzen 5 7600X, 2x8 Hyperx RAM, Gigabyte A620M Motherboard. My gpu is RTX 3060 Ti with 550W Corsair Bronze Power Supply. I've recently encountered the problem when it comes to more demanding games thats my PC completly turns off (black screen) after some time with only RAM staying lit up and it won't boot unless I reflip the switch on my power supply back on. I've tried MSI Afterburner to see what is causing the issue. My temps look like this: CPU idles on background at around 35C and GPU at around 45C. While I was in game and GPU was on 80-100% load it was around 67C and CPU on 25% load was around 65C. After that certain temps my PC completly turned off.. Tried it a few times same thing happen at around this exact temperatures again.
What might be causing the issue? Btw, thermal paste is applied properly on my CPU (I think) and my GPU has been cleaned regularly and is around 1.5 years old. PC has 4 case fans in total and CPU cooler is beQuiet Pure Rock 2.

Thanks for reading and if you might have a solution please let me know!

550W Corsair Bronze Power Supply
Corsair is the brand of the unit, while 550W is the advertised wattage of the unit. Bronze is the advertised 80+ efficiency rating of the unit. How old is the PSU?

Question - PC doesn’t show display on monitor

Pc newbie here, Recently I’ve ordered new parts for my PC. New motherboard, CPU, RAM and an SSD. I’m using my old graphics card for previous RIG, power supply and HDD. When it came to testing out after finishing the build whether my pc boots or not it turns on but there is no display on monitor...

You didn't respond to that thread but did you recycle your older OS drive?

PSU is around 4 years old now. I've fixed this "Not Showing Display" issue by taking it to the PC specialist and he said the problem was with motherboard so he unlocked the motherboard with an USB because it was "Bitlocked" by the manufacturer.
