Morning. Went to turn on pc. Power came on, fans spinning but that's it. Worked a few days ago..the amber and red light for CPU and dram cokes on and stays on. See picture.
I have a Ryzen 7700, Rx 9070, 32gb 6000mhaz ram and the Asus tuf 850 power supply. My mobo is asrock b850 pro rs WiFi. I updated the bios to latest one when I built the pc
All items new. Had the system for a couple of months now and built by myself.
What I have done so far .
Check all connections on psu and mobo.
Taken each piece of ram out and tried in each ram slot
Taken CMOS battery out and put back in.
I obviously don't have a spare CPU to check.. just wondering is there anything else I could try.
With all this. Pc still turns on, fan spin but not display.
I have ruled out GPU as the light for it isn't on ?
Many thanks

No, you haven't ruled out the GPU. Your 7700 has an internal GPU so try pulling the RX 9070 and plugging the video cable into the motherboard.

Also, try testing the motherboard outside the case.

IIRC there have been a few instances of Asrock motherboards killing Ryzen CPUs, but they've mainly been the 9800X3D. You might want to read further on that.
 
Sounds like motherboard or CPU.

Things to try

- Remove and re seat the ram or try the other 2 slots of the motherboard
- Re seat all PSU cables to the motherboard
 
So what I have done today. Took GPU out. Swapped with a working GPU. Also tried with different ram slots with each stick of ram (don't have ddr 5 spare)
Took GPU out and tried using onboard GPU.
Also took CPU out. See pictures. They all look ok.
And then tried with both GPU and ram and ram slots.
All I get is lights on RGB fan, and fans spinning on aio and case fans. (Same as before) And both lights still on.
What now ? Test motherboard ?
 
As mentioned earlier, try the motherboard out of the case. Put it on the motherboard box not the anti-static bag.

Reset CMOS in case igpu is disabled.

What thermal paste did you use?

Looks like some is close to getting on the pins.

Did you actually try it without a GPU using the onboard graphics?

Also you could use the BIOS flashback function to see if the board responds to being flashed, and check if you are booting with a single RAM module that it is in the correct slot and test both of them .

I've clean it off now. The paste I am using artic mx 6. Resetting CMOS is that just taking battery out for a a while then reinserting

Yes took GPU out.. tried ram in all slots (single stick at a time )
Will have to try bios flash back.

yes, just remove power from the motherboard and press the power button for a couple of seconds then remove battery for about 10 mins.

Did not think the paste was the problem, but thought i should point it out for when you put the CPU back in.
