Hello, need help on Asus GTX 1050 Ti PWM
Trouble PEX 0 volt, VDDC 0 volt, Memory also 0 volt.
AND gate (marking VE, 74LVC1G08GW) near PEX Inductor, at U3, has 3.3v in one pin and has 0 volt in other pin

1. can u help me where i start to trace pin with 0 volt on AND gate come from?
2. What power came (ON) first? PEX or Memory volt?
can u help me how to solve problem. Thanks for u help

You have to measure 5V regulator and all other chokes you can find. Measure also all resistances on them. This is the beginning. Check fuses if any, check supply voltages before regulators...

yes. already done that. 12v 5v 3.3v and 1.8v power all ready (ON)

I also asked you about resistances. Please measure them.
