I am trying to get my RPi4B(4GB) powered ON with a power supply but am frustrated with the results. I found a workaround to this problem, which is that I can power on the Pi4B with a type-C USB cable connected to a desktop USB port, but I do not want to continue doing this. Since powering on the Pi4B this way, I have installed Raspbian OS and Kali Linux on it, both of which run smoothly.
I used the Raspberry Pi's official charger with 5.1V/3A output and it just doesn't power it on. Some different cables(connecting via the desktop USB port) that i used earlier to check the Pi4B showed the low power symbol and other experiments with the Power(like using a powerbank, instead!) smoked 2 of my Class 10 memory cards.
I found success with the Samsung cable so I subsequently stopped looking.
The only way my VGA monitor responds to the RPi4 is if I connect the power from the desktop USB port. Also I am doing this in my college and this works on just 1 monitor(/23), which is not an HDMI monitor [1440x900]. Although I haven't changed anything in the config file to set this resolution for even boost hdmi, it just works! Also tried using a 5V/3.1A[shorturl.at/AGLVW] and that doesn't work for me either. I have another RPi4B 2GB variant which responds exactly the same way to all the issues i mentioned above.
As of now i have kept the RPi4 aside(ever since the last SD card burnt), please tell me how i can get it running again without having to rely on a a desktop USB port everytime...
Edit1: The official PSU is not powering it on. I do not need a cable when i can use it directly after connecting it to a power socket. Issue is it does not work with any other charger either. The only way it works is if I put the PSU away from another charger and use it's cable from the desktop USB port.
Also, I did use another (Official)PSU and yet the it didn't power on, so i don't think the psu is the issue.
