Hi everyone, i have short on my graphic card on 3.3v line, so i desoldered the crystal and short still exist. I try find it with my power supply but, rails inside pcb is hot, but not any elements, i cant find what is broken. I dont have thermal camera. Have you any advice for me?

I would advise you not to inject 3.3V into the graphics card unless you are trying to kill it.

You need to inject a safe voltage into 3.3V (such as 0.7V) and see if that voltage appears on any of the other voltage rails first (1.8V, PEX etc)

The crystal or lack of one should not affect the voltage rails
