Plug in a keyboard and see if the lock lights flash.

On the video that I sent you the keyboard is already plugged in

Do the lock lights flash?

Now the DRAM_LED is yellow always

Remove the current stick or ram and try the other and see if it does the same thing.

Same. The dram_led still yellow

Not good news then either you have 2 bad sticks of ram(unlikely) or the motherboard or cpu(memory controller is part of the cpu) has failed. Given the way the cpu cooler is and was mounted that would be my prime suspect.

Hail Mary, remove the cpu cooler and reseat the cpu and check for any bent pins in the cpu socket.

Ok so I tried with only one ram and there no yellow light anymore. The power supply fan work too. But nothing happens on my monitor

So you can see the bios?

Yes. But I always need to reset with my screwdriver when I turn on the power supply. Otherwise it's working!

 

[bignastyid]

reset with my screwdriver

??? reset the cmos or use the screw driver to short the power switch pins?

The PWRSW

The PWRSW

Yes, that's how you turn it on with out the power switch from the case attached. The switch on the PSU only turns on the PSU it does not turn on the system.

So now install the 2nd ram stick in slot 4(furthest from the cpu) and see if you can still get to the bios. Also in the bios check your cpu temp to make sure the cpu cooler is getting good contact.

I think one of the ram is dead because the DRAM stay in yellow!
When I remove this ram and turn on the computer the DRAM doesn't keep yellow. But the computer doesn't show the bios anymore 🙁

Remove the suspect stick and reset bios and see if it will complete post again.

I reset the bios. The DRAM is not yellow anymore. The power supply and all fans work. But still no bios showing up on the monitor. Even the keyboard doesn't turn on

Hello, I hope you are doing well.
After many tries, it's still doesn't work. My monitor can't detect the source to HDMI. There is no led. The ram work, the CPU work and even if I charge my phone through the USB it is work. Weirdly the keyboard can't be connected. I reset the motherboard and still doesn't work

 

[bignastyid]

Try reinstalling the gpu, maybe just an issue with the igpu.

Hello,
how are you?

I was on vacation, so I could not fix it. Today I tried again and it still does not work. The strange thing is when I turn on the computer, my monitor turns on automatically but nothing is detected.

Thank you

I solved the problem
For the next person who needs the solution. For me the problem came from my CPU. I had put in too much thermal paste so I put in a little less and it worked.
