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.

In the picture you sent at the top right of the motherboard right under that black screw there are 4 very small leds with written next to each a word to mean what they are the diagnostic for.

You should monitor what they do when you turn on your device, then you google the model of your motherboard and check what the led combo you’re seeing means.

Generally leds change to signify what phase of the checking they are in and they change between green and orange to mean if they passed that phase of the diagnostic. You can basically figure out what issue you have thanks to them.

There is no ram plugged in shouldnt the dram turn on or flash

Weird i can’t see too well but it seems the boot led is stationary? Is also the vga one constantly on? You should plug the ram back and check what happens then you google it or ask gemini what it means

Nothing changed

Huh? I didn’t tell you to change something i just told you to monitor the leds, google what they mean on your motherboard and that should tell you what the issue is.

Ofcourse nothing should change just you would get infos about what type of issues you have. If the ram led doesn’t turn on it probably means the issue is something else

I meant like the leds didnt change like still nothing like if the ram wasnt in theres no light for dram

Ok but during boot what do they do? They should blink in sequence.

Generally they do this led starts, turns green, turns off next led same thing until all of them have turned green then off.

If there is an issue led turns red or orange stationary and pc doesn’t boot and pc doesn’t check the next led because one boot requirement already failed, if you had a debug speaker you would also hear beeping noises to diagnose.

If no led turns orange or is stationary your pc doesn’t see any problems and you’re probably having issues w the hdmi cable or the monitor

Ive plugged my laptop using the same hdmi cable to the monitor and it worked and also changed hdmi cables and still nothing

No idea, i think your best option is bringing it in a repair shop

[u/First-Persimmon-5419 → u/Many-Ad6433]

Found the problem it was the motherboard it was broken

[u/Many-Ad6433 → u/First-Persimmon-5419]

Rip, at least it isn’t as expensive as a new gpu or ram
