Burnt SMD component dag7bdmb8f0 rev d ryzen cpu

Hi guys!.
Does anyone knows what component is burnt in pictures ? (Orange circle). Prior to get burnt PC was turning on but could last 20seconds-5 mins before random shut down occur . After this , trying to turning on could result in no display output , fan not turning on ,power button led turned on and after 10-15secs restart again. Las try resulted in this SMD component burnt , I think was the culprit of the main problem.
Cheers!

I think I found a schematic.

Confirm that the feedback resistors (R1 & R2) match on the logic board. If the values match, then the regulator is likely the same part number even though it is a schematic from a different version.

Believe the burnt part is PU851 (SOT23-6 package) in the schematic.
