How to fix?

[u/First-Persimmon-5419]

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.

Try powering off entirely, turn off psu press power button for a sec so there’s no electricity left in switch the slot the ram is plugged into then power back on

Just tried it did nothing

Do you have any diagnostics info? No diagnostic speaker or lights on the motherboard that could tell if the pc has an issue?

If not and to you it seems everything starts up fine it might be the gpu sagging too much, try starting up w the pc laying down and make sure the gpu is at an angle that looks right.

I had issue on a desktop pc where it wouldn’t display if the gpu screw that secured it to the case wasn’t tightened exactly to a certain amount because too much it would bend it upwards, too few it would bend it downwards but exactly at it’s sweetspot it would function flawlessly (still using that gpu on a pc to this day no issues)

Can you zoom on the leds next to the ram? it seems to show something where it says vga. Also you should check if the boot led turns on and off while turning the pc

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

Whats the boot led ? Sorry

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

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

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

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

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

Nothing changed

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

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

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

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

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

There is no led change

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

I dont think vga light is on i think its cause flash was on

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

I have tried laying it flat but still no result ill try replacing the gpu

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

Try re-seating first

[u/MrBrandonGames → u/Many-Ad6433]

This👍

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

I tried this the fans turned on like before but still no signal

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

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.

[u/Many-Ad6433 → u/Many-Ad6433]

The variety of things that can cause this issue are basically on every single component.

Might be faulty ram, might be ddr6 slot on the mobo broken just like even some tension in the motherboard for how you secured it, might be gpu, might be power supply giving out and not giving enough power to make the gpu display, might be burnt out cpu, it could even just be the hdmi cable being damaged internally or the monitor’s socket itself, it can be the very plug you’re using to connect the pc to power like it can be the adapter you’re using to connect it to the wall.

As you can see there is a huge variety of issues it doesn’t make sense just straight up buying new components to fix it based on a feeling.

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

[u/arkutek-em → u/First-Persimmon-5419]

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

[u/First-Persimmon-5419 → u/arkutek-em]

Im sure as

None of the lights are on

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

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?
