Just finished a new build last night:
ASRock B450 Steel Legend MB, AMD Ryzen 3 2200G, no additional GPU
Symptoms: Computer powers up, but does not get to post, no beeps.
Runs for about 15 seconds, all fans, lights, all connections seem to run normally, then it shuts down, restarts itself and continues cycling.
Timeline of troubleshooting:
- Cleared CMOS and also reseated the battery
- Unplugged everything one by one, re-testing. Finally Isolated the problem down to the 8 pin power connector. When not plugged the computer does not shut down.
- Tested the PSU with a DMM, and then also with another board, all good.
- Took the MB out of the case, same symptoms , so not shorting
- Checked the connection between the heat sink and the CPU. Thermal paste is not spread very evenly but there seems to be enough of it. Did not reapply. Otherwise it all seems tight...
Is it possible that it shuts down just because of the heat sink, thermal paste? So quickly?
I can return the CPU and/or the MB, which one would you try first? Or any other testing suggestions?
