Pc suddenly doesn't post anymore.

[Gravely]

Yesterday it was working fine and today it's not doing anything.

 

Keyboard leds aren't lighting up and monitor isn't getting signal.

Case fans are running, so is the aio fans and the pump

 

I tried removing cmos and reseating ram.

 

 

Do I now start removing drives until it boots?

 

 

System:

Aorus b660 elite ax

R7 7800x3d

Rx 7900XT

Corsair 850w

Try removing all non vital USB devices plugged into the PC and see if that'll allow it to boot. Does your Motherboard have beep codes or onboard LED indicators on system status? 

Recheck all PSU cables to make sure everything is plugged in snuggly, Try booting with only one stick of ram. Test different sticks if one doesn't work. 
Could be a graphics card problem as well, try booting via onboard graphics.

And please give us a full system run down including ram so we can better troubleshoot your problem.

No i haven't updated my bios. I think

 

Maybe it was in the adrenalin updater? I've only recently switched over to amd, and I'm not sure if I have to update manually.

I'm not sure what led I should be looking at. But it for sure doesn't have a beep.

 

I tried with 1 ram in a previously unused slot/channel, didn't work.

 

Removing gpu power doesn't do anything.

 

I do have the dram led lighting up.

 

Also, since I got it, I've seen a flash at the bottom of my board whenever I'd flip the switch on the back. I've always thought it's a led or something. I made a vid, will upload. Can't upload here because too large.

Video of flash when I flip switch.

Only occurs when I cut power completely.

Also what do you mean by full rundown?

As in, all hardware in detail?

Not sure what that is, doesn't look like a LED to me... not promising lol.

Can you send the board for a RMA? I'd bet the board is the culprit here.

Yes all the hardware in your system.

Umm it's working again now.. I put 1 ram stick in the last slot, reconnected power to gpu and board and flipped the switch a couple of times, and now it's running...

 

I dont get it

[Gravely]

I turned it off to put the second ram in, and now it's back to dram led on and thats it

Very good, looks like you've solved your problem. One stick of ram is dead/faulty.

It's the ram I took out when I tried it on a single stick, and it didn't work then.

 

Now I took the 'faulty' out again, and still nothing.

 

Dram led is still on.

Ok I'm getting confused with your wording.

Let me get this straight you put in one stick on the last slot on the motherboard and it worked. Then you put in the second stick while the first one is still in, and then it failed to post. Then you took out the second stick, and now the system won't post with the single stick?

Okay so earlier you asked to try with 1 stick, I did that. Then later I put that same stick the original slot(4) (i moved to slot 1/3 for testing in stead of original 2/4), then it suddenly worked, then I added the other stick again (slot 2), it didn't work, and now I removed the stick in slot 2 again and it still doesn't work.

 

Does that clarify it for you?

I've done some switching around with my ram hahah

See, there is a led in that exact spot. That's what's making me think it's not a short.

 

Also it's now working on the other ram stick... what..

And the led apparently stays on even if the rest of the system is off...???
