HELP ME Power on when reheated.

[fhulgzz]

Hi!
Meron akong weird problem.
Desktop PC, ayaw mag power on but pag binugahan ko ng hot air ang board tsaka pa xa mag power on. At kahit ioff mo, madali nalang xa mag power on, one click lang.
Pero pag kinabukasan ayaw nanaman, so hot air ko ulit at working normally nanaman after hot air.

Meron din ako isang preheater ng iphone yung iRepair MS1 ganon din problem. Pag ihot air mo tsaka pa mag power on.

Basically pag cold ung board ayaw mag on.

Na check ko lahat ng components ok naman. Nag resolder na ako ng mga components, ICs, big caps etc...

QUESTIONS:
Anong possible components kaya ang salarin?
Sa mga experience nyo sa electronics anong components mostly ang nag cause ng ganitong problem?

Thanks in advance sa maka share ng idea.

nasubukan ko rin yan, in a certain phone mobo kunting alog or reheat bago magtuloy in powering on the unit;

maybe possible is some components need to replace upang mag tuloy or running flows in a normal stage for good stable supply output
