Hi there, hope this is the right place for something like this.
So today I used my computer like normal, everything was fine this morning.
Then after a brief walk I came home and it won’t turn on since.
When I click the power button there is the normal click sound of the psu and nothing happens.
My keyboard lights up, the ethernet port lights up, but other than that - nothing. Already tried to remove the ram, the graphics card (just removing the power cable of it turns on its red light), removing just the cpu power cable does turn on the motherboars red status light, but non of the fans or other status leds light up.
My build is not new and other than the
keyboard I did not change anything lately.
The build consists of:
Asus ROG Strix B550 A
Ryzen 5600x
32 GB Ram (Crucial ballistix)
Asus RTX 3060ti
Corsair RM650 PSU
I also unplugged the psu for a while. It makes a slight buzzy noise after powering the computer, but I do not know if this is normal.
Can anybody help me please?
Thank you.

Be sure to test the power supply before going too far down the rabbit hole.
Thank you, I just did this. Bridging the pins does nothing, it just clicks and no fan movement what so ever. So it seems the psu died. I try to get a second psu, but I may be oit of luck this weekend.
When your pc dies it’s ALWAYS during the week-end or just after the stores close
Yeah, exactly. The one store I went to, right before closing did not have any psu’s. So I ordered one for next week.
You have to start in order of operation. Number 1 is the PSU itself. If you motherboard does nothing at all, no lights, no fan movement, no post boot anything then your PSU as expired.
After that you remove components and try again. Your case sounds like it’s either a PSU or a CPU.
Get some thermal paste and remove the CPU and check for damage on it. Pins can actually melt off of it gets hot enough.
Yeah, Maybe one of the rails on the PSU broke? Can something like this happen? Some parts of the motherboard seem to get some power but, I do not get any of the main status leds.
I will try to look at the cpu later, I try to get a second psu for testing…
I also unplugged the psu for a while. It makes a slight buzzy noise after powering the computer, but I do not know if this is normal.
I’d recommend starting with the PSU. A buzzing noise is not a good sign. This article has details on how you can test your PSU: https://www.howtogeek.com/172933/how-can-i-test-my-computers-power-supply/
You can perform a basic test with just a paper clip or a bit of 16 or 18 gauge wire.
It sounds like the PSU is giving some power, given that the keyboard lights up. The issue could be isolated to one or more rails, e.g. it’s not delivering anything / enough on the 12V or 3.3V rail. I’m guessing 5V is OK since that’s USB voltage and your USB keyboard gets power. You’d need a multimeter to check individual power pins on the PSU connector.
Edit: if you have access to a second PC, you can swap PSUs between them. If the problem follows the PSU then that’s the faulty component. If the problem stays with the original PC then it’s likely motherboard, CPU or RAM.
If you can determine that the PSU is OK then the next step is to try booting with the bare minimum amount of hardware. That’s motherboard, CPU and one stick of RAM. If that won’t boot then you try with a different RAM. If it still won’t boot then the issue is motherboard or CPU. Before you replace either of those expensive components, try replacing the cheap CMOS battery as another poster recommended.
Thanks, I did this test and it just clicks and buzzes, without fan movement. But I did throw away my old psu while moving and I may have to wait for next week.
The last time something like this happened to me it was an Asus motherboard as well, I had to change the CMOS battery.
But it was way older hardware than today and after coming back from weeks of holidays with the PC switched off.
Thanks. I tried changing it, but sadly did not change anything.
Plug everything back in, and unplug the PW+ and PW- connectors from the motherboard.
Use a flat screwdriver to touch both of them at the same time and see if it boots. If it does, either is one of those two cables, or the power button itself.
So, I tried this, it does the same click and thereafter a buzzing sound, so power bitton seems to work.

That was my first thought, because for whatever reason my computer wont start when my screen is turned off. You have to power cycle it with the screen on to get it to work. Haven’t had this with older computers. But when this happens the leds still work.
