I am trying to take each one out and back in but I can’t take out the 24 pin like I don’t know how it’s like stuckOk so what you are left with is the old troubleshooting guide lines. Pulling the plug out of psu and replacing it. Try restart. Then you will have to check every wire attached to the psu to make sure they are seated. Then you will have to follow them and make sure each one is seated in its slot. Paying close attention to the motherboard and cpu power plugs. If you are not getting any power, it will either be your motherboard had the old static electricity death blow. Or your psu has died. Do you have another psu you can try to see if its your board or the psu?
That could be your culprit if it was jammed in incorrectly. Smell it and see if you can smell any burnt smell make sure it didn"t arc or something like that. Also is the inside of your computer very clean or is their dust everywhere?I am trying to take each one out and back in but I can’t take out the 24 pin like I don’t know how it’s like stuck
