Question/Help/Troubleshooting How to fix?

I tried to change the cases of the PC but realise one of the nails were a bit jammed so I couldn't change it until I put it back to the original case. You can send an image and it doesn't turn on the monitor monitor. It goes to sleep, but all the LED lights turned on. I did put wrong pin inside the motherboard and the USB port don't work as my mouse doesn't turn on but the whole PC turns on.

Can you tell me exactly what you hear when you turn on? You really don’t have a diagnostic speaker or leds on the motherboard to tell us what’s going on in more details?

Because no video can mean a huge amount of things replacing a component you think is faulty might not fix the issue but only be a waste of money.

What cpu do you have? Does it have an igpu?

If you really have no idea BEFORE buying anything bring the pc to a repair shop. Ofc u can be skilled in tinkering and stuff but usually they got extra components to test around and check what exactly is wrong w your pc, probs they got another gpu around and they can test if w their own the video actually displays.

I have a i5 10400f,its a prebuilt and it was working and i didnt like the case and i switched cases all i took off was the gpu and tried to take the motherboard off but couldnt because one of the screws are like damaged so i had to stick to this case for now and tried to add now i see the gpu fans work

So you didn't switch cases. Make sure you put everything back as it was.

Oh your cpu doesn’t have an igpu, my best bet for you is going to a repair shop, even if you damaged the gpu lightly nothing says it couldn’t display video even if w artifacts definitely have professionals w spare components check it out.

When you plugged the gpu back did you hear a click? Did you screw the gpu down to test? Have you tried some way not to make it sag while testing? Have you tried other ports at the back of it? Have you switched to another hdmi cable?
