My computer cannot enter bios whatsoever

[Miftah]

Hello everyone!

Can everyone help me out with my computer? My system currently cannot enter bios nor have anything displayed on the screen.

This problem started a few months back, that time everytime I turn on my pc the fan make a loud noise especially the one on the gpu.

Like you make them spin the highest setting, but gradually the fan slow down and the noise vanished and after that, the starting screen with all the text come up so I just can use my pc like a normal.

(Yea, I know that something wrong atp, but I just ignore them since I can use the pc normally)

 

But recently, I decided to clean up my pc and I do not do anything that I believe can harm any hardware on it. Just simply brushing the dust away with my paint brush (lol).

 

And after I connect all the cable again and press power on, the pc turn on like normal but the fan noise and speed didn't vanished after a few seconds like before and just going through full a few minutes.

I don't know how long they can get since after just a few minutes, I decided to turn it off and I already try restarting them and the result are same.

 

In the past, I came across the same problem and after bring my pc into computer shop. They told me that the motherboard is f*ckup because electricity that often dies suddenly on my house (because of excess power of course). So we decided to change them.

And if you figure it out already, I think this problem happen because the same reason. But this time, I don't think it's because the motherboard that got f-up. Since I already try switching the mobo and the result are the same.

 

My feeling told me that, either the cpu that got f-up or neither the ram or gpu.

But it's can be the power supply as well.

I don't know if this helpful but I noticed that this time, the light from my nmve ssd didn't show up as well. So I think the system can't even read or start the whole program itself.

This make me feel that my cpu is the problem but it's just my feeling.

 

So with all of this information, i really appreciate some suggestions or guess about damaged parts on this case.

 

Note : yes I already bought ups (too late sadly )

 

If only the nearest computer shop from my place isn't 45min drive.  Dang it

try with one ram stick at a time. hopefully its just a bad stick that was messed up.

Specs ?

That is a bad idea can may have caused hardware damage. Unlikely, but still a possibility. Especially if the brush has synthetic bristles
In the future, just use canned air

Let it run for 15minutes. It might be trying to recover settings and stuff. Or do memory training. 
This won't hurt anything

A UPS can help protect your hardware from this kind of wear and tear. Good job getting one!

Decent instincts. I will say that it's unlikely to be the CPU (unless it's a 13/14th gen intel or potentially the AMD 9800x3d but that's a developing story).
I'd suspect the PSU, but you're saying that it is at least powering on. This doesn't eliminate the potential for a *mostly* dead PSU, but it should be allowing us to get some idea of the problem.

It could also easily be the GPU or RAM, they are the most delicate parts of the PC. But my first-ish suspect for broken hardware is gonna be another dead board. 
One thing we need to know is what debug info the mobo is giving you. Do you have a beep code, debug code, or debug LEDs you can get out of it? Check the mobo manual. As leclod said, Specs will help

Finally, this started happening when you physically interacted with the inside of the machine. A very good step here is to completely disassemble the tower, then rebuild the minimum viable components on a cardboard box and see if you can get it to POST


ETA: oh, and dumb question, I know, but can you test the monitor with the same port and cable with a different device? All those brownouts may have damaged it an not the PC
