The PSU works, but shortly after powering on (either in the G5, or by shorting the power-on pin to ground) it begins buzzing loudly. It also makes the LED lights connected to the same circuit flicker. It's definitely a buzzing, not a high pitched whine.
The buzzing seems to come from the high voltage side of the board, perhaps from the white relay. Could the relay be bad, or could the 5V supply be bad enough that it's unable to keep the relay on? Any pointers to help isolate the issue? Thanks!

I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.
All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..
How can I extend its lifespan? Could reflow help?
It has ryzen 5 5500h, rtx 2050, no soldered ram.
Example of the artifacts:

Hey I am having Asus Rog strix g15 g513ih hn0865 and it's having display issues while running on igpu. Works fine when I open any game or whatsapp windows application. The issues are :
Black screen, freeze
The weird thing is that when as long as the laptop is running on igpu the problem keeps happening. But as soon as I open any game or whatsapp windows application, the laptop works completely fine.
When the screen freeze or black screen I used to move the display lid up and down and it usually works like that.
So can anyone tell me what would be the possible cause?... -
Hello, This is my first post so please forgive me if I miss out some vital info.
I have a problem with my HP1955L monitor from 2005.
The first thing to say is that it is still basically working, ie the picture is fine.
However it makes an electrical buzzing sound. I know all monitors make some some of hum, but this is louder and more of a buzz.
The volume of the noise seems to be dependent on how hard the monitor is working; switched on with a blank screen -> no sound; small dialog (like OSD only) -> minor buzzing; full screen picture -> loud buzzing.
