    RX 6700 XT PowerColor not recognized in any OS

    Hello,

    The title explains the issue. The additional information is:

    - GPU was never disassembled
    - not recognized in Windows/Linux, not even with error, totally not recognized like it's not plugged in
    - GPU fans don't spin but work. When I turn on the system, the fans twitch for that second when I press the power button. Same thing happens when I power off the system.
    - GPU does not get hot no matter for how long I let it run even though not recognized

    What I have to done so far:
    - played with the BIOS switch without any luck. OC/SILENT no result
    - opened the GPU replaced thermal paste and pads, inspected the hardware. GPU looks like brand new, no burns, corrosion etc. No luck.

    If there is anything else I can provide to resolve the issue, let me know. I will provide all necessary information.

          Maybe I am watching the wrong ones because I am unable to find a short circuit. Would you recommend any guide? I am trying to find out which component should be tested in which mode with the multimeter so I can get the proper readings. Sometimes continuity mode could mislead you.

          Thanks in advance.

              Where can I find schematics of this GPU with all the correct values/measurements for resistance etc.?

                  That's the short according to the multimeter. Diode mode, 0.021v is what I'm getting. The one on the left reads 0.64v. How can I find the correct shorted component?

                      That circled 1R0 component is an inductor, my dude. You should get very low resistance across that. It should not short between either side and a ground plane, however.

                          dont need to have short. just measure voltages to know where card have stuck

                              RTX3090 working fine but fans not spinning
                              by emil_t
                              Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....
