Hello,

I recently swapped my stock ventirad (AMD Stealth Wraith) with a Cooler Master 240rgb water-cooling.

I didn't need to disassemble everything, I just removed the ram to have more space, the motherboard stayed in the case, same for all the cables, I didn't unplug anything.

Except that when I turn on my computer, I have no signal. The lights come on, the fans are all running, the RGB of the pump comes on, the LEDs of the motherboard come on, the RGB of my keyboard and my mouse come on, but 0 signal. I don't understand what's going on.

I removed and put back the ram, I removed and put back the graphic card, checked the display port of my screen, nothing happens. I tried with the HDMI output but I have nothing either.

My pump is making noise, my fans are running fine, and I don't know what to do anymore.

I'm going to give it one more try with my old monitor on HDMI but I don't think it will make a difference.

My only thought is that there is a PRESSURE problem detected by the cpu which thinks it has no cooler on top, but I checked it out and my INSTALL is fine, tight, and I put an adequate amount of thermal paste.

I switched back to the stock cooler and nothing. I have no signal anymore.
For those who ask:

Aorus B550i Pro AX
R5 3600
RTX 2060
16GB of ram

I'm starting to despair. This pc was WORKING perfectly and it is my only work tool for my studies as well as my only entertainment because it allows me to connect and play with my friends who are far away. I'm starting to fear that an important component such as the GPU or the CPU has died without reason, and I don't have the money to buy one, especially in the current situation.

Unfortunatley this could be caused by a LOT of issues and without spare parts could be quite difficult to diagnose.

Have you tried booting with only 1 stick of RAM at a time, trying DIFFERENT slots? (Assuming that you have more than 1)
Unfortunatly the 3600 doesn't have integrated graphics so you can't boot without the graphics card.
You could try a CMOS reset (although I doubt that this would be helpful in this situation)
If you have a spare power supply give that a go.
Other than that try the most minimal boot possible (CPU + RAM (1 stick) + GPU & nothing else)

I don't suppose that you have an old case speaker to see if the motherboard generates any fault codes? For a motherboard without a Q-code display I would consider this an investment in itself.

I'm really sorry for asking this but do you definitely have the CPU fan connected the CPU_FAN connector not the CASE_FAN?
