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

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.

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

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 .

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

Or save your money and just RMA the CPU?

If the new CPU works, it's not the mobo.
If the new CPU doesn't work then it's probably the mobo.

All the disassembly and rebuilding just increases the chances you may inadvertently damage another component. Yes the chances are extremely low, but it's not zero.

Good idea.. will get a new CPU and take it from there.
 
Err. What?! Just booted..took ages though..
Had the same motherboard lights on.. went downstairs after looking at a black screen and the 2 lights on the motherboard for about 15-20 seconds.. when I got back up was on window loading screen

Because the website in question charges marketplace sellers a fee for refunds, and if the seller is using their warehousing and fulfilment services, the website also charges them return processing and restocking fees.

I just saw this.. read small print and there something like a 20% restock fee or something silly like that..
Looks like I will be sticking with the 9600x and sell the 7700 when I get it back
