Yoo, i've bought a new computer case and after I imported all my components from the older to the new one, i have a big issue: none of the USB slots works anymore. Also, my computer won't shut down properly anymore: windows turns off normally but the fans and leds won't turn off.
At first I thought the JUSB cable (that 20 pins cable you plug on the mobo) was broken, I tried to plug on JUSB3 and JUSB4 slots but none worked. Then I brouth all my stuff back to my old pc case and and guess what... it didn't fix the problem!
So now i'm completely lost I just don't know what the fuck to do anymore. If only the USB slots didn't work i'd assume the mobo would be dead somehow, but that shutdown issue leads me to think the issue could be the PSU too...
Why the problem stills happens with my old case? All the same components, was working before, why it doesn't anymore?
If someone ever had that issue please help me to solve it
For some reason when I seek on internet everyone seemed to have that issue with MSI motherboards (whatever the model) and i do have a MSI mobo (Z270 Gaming M3). It's only 2 years old it's surprising that it would already be broken.
Note that plenty of people proposed solutions such as updating bios etc but there again, exact same stuff, it has no reason not to work anymore. Nobody solved the issue and most of the forum topics were lost and forgotten...
Edit: also JUSB1 and JUSB2 for old 2.0 won't work either, neither of my 2.0 or 3.0 are working.
