OS is on M.2 and I’ve since disconnected all the HDD’s.

So PC has been up and running just fine and dandy until earlier today. I had delivered a GFX card, Powercolor 6700 xt. I powered down the system, installed the card, connected the 6&8 pin and when I turned it back on all the lights come on but no body is home.

No post
No keyboard lights
No display on out

I have tried HDMI and display port between onboard and the GFX.

I have removed the GFX

I have tried removing all the RAM

I have jumped CMOS

I have removed CMOS battery

I have completely stripped the PC down as far as removing every single component from the case and the Mobo. Cleaning and reapplying thermal paste.

I power the PC on, lights come on, fans spin, RAM and fans spin and RGB is on. After 20secs or so the system appears to shutdown and then restart again.

I am completely at a loss. The only other thing I can think to do is to build it outside the case as there could be a short somewhere?

Is my motherboard dead?

I would unplug everything, just have the psu connected, 1 stick of ram. No fans or lights or anything else.

Can you try a BIOS flashback to the latest bios? Board may not support it apologies I haven’t checked.

Otherwise, it does sound like a potentially dead MB.

It could also be the PSU, but my experience of a faulty PSU is that they won’t operate at all, as in, you get lights on but press start and ‘click’ nothing. Where as yours sounds like it starts up.

It starts in so much as lights on, fans spinnning but nothing else. Also something I noticed which may or may not be relevant. The motherboard usually has a LED trace in the motherboard, kinda looks like you can see a lit up power connection but it’s like a cable in the board? My old ASUS Mobo has the same thing. Anyway, that is no longer lit.

Did you run the GPU off one cable from the PSU or two? If you ran it from one cable and used a pigtail connector I wonder if you have damaged the PSU. Have you tried another PSU? Have you checked the connections at the PSU end if it's a modular PSU?

Hang on, it's a Gigabyte PSU - didn't they have all sorts of problems quite recently?

I did run the GFX off a Y split, but only because I read the card only draws about 200 under max load. I think there was problems with Gigabyte in the recent past but this one does seem to be working.

I’ve ordered a replacement board now anyway, comes on Saturday. If that doesn’t work then next thing will be to try and get my hands on a different PSU. What a nightmare!

The PSU is a Gigabyte P1000GM, fully modular

Your problem seems very similar to mine.
Have you got any success running just the CPU+RAM+drive (main GPU removed) and using IGPU output?

Unfortunately no. It was the one if the 1st things I tried. What system has this happened to you on, when did it start happening for you?

Okay so I ran out to my local hardware shop, got me a motherboard speaker.

I get 4 long beeps then PC turns off. Annoyingly Gigabyte doesn't offer any information on their website about what the beeps mean for my motherboard :(

If you have a PC running on iGPU then the BIOS will be configured for it to be the primary VGA.
If you want to add a dGPU then you must first boot with monitor connected to mobo, enter BIOS, change dGPU to primary and then reboot, swapping monitor into dGPU.

It doesn’t post with or without the GPU. When I initially booted after installing the monitor was still connected to the motherboard output but it was already No POST at that stage. Any further trouble shooting has drawn a blank. I cannot access BIOS.

bios for fixing no display with a 3060 card, might affect a similar spec from amd like 6700xt?

btw u checked if its shorting on anything?

In manual.

SPEAK (Speaker): Connects to the speaker on the chassis front panel. The system reports system startup status by issuing a beep code. One single short beep will be heard if no problem is detected at system startup.

I get 4 long beeps? There’s nothing anywhere about that. I did also look at the more premium versions of the same board to see if their manuals were better but only contained the same information
 
Okay. So the new board is coming today so I stripped everything from the Mobo, only thing plugged into was the Mobo speaker, keyboard and monitor. Ram and CPU removed.

No post, no display output. I think she’s dead. Just waiting for the Amazon man now. Will post back if I get her working.
 
The Mobo I have can boot without a CPU.

Okay fellas, so try and figure this one out. New motherboard installed and I am still facing the same issue.

Is it likely to be the PSU? I’m so annoyed right now
 
Thank you for your replies.

I’ve reached out and managed to find someone local who is lending me their PSU for testing. I’ve also ordered a new PSU but can cancel that order based on tonight.

I hadn’t thought about just leaving it on for a while, I’ll go and try that now. I couldn’t see it being the CPU but then with my luck so far it absolutely will be that.
 
I’ve had the PC on now since you last posted, it’s still doing the 4 beeps. Mad! Anyhow, just waiting for the wife to get home so I can run over and nab this other PSU.

I’ve never looked in MM before, will have a nosey.
 
Okay. Got a loaner PSU, same behaviour.

Now the only thing I have not done is build it outside the case to rule out a short. So guess what I’m doing now.
 
Okay.

So I’ve build it on the motherboard box. I stick of ram, CPU + cooler and drive. 4 FLIPPING beeps. WTH am I going to do now? Is my CPU dead, if so why the hell did it die? Nothing touched the CPU or the cooler when I was installing the GFX card, is this something that happens?

I also tried with removing the CPU and while the light come on their is no beeping but there’s also no screen I can access.

If that's with the new motherboard and different psu then yes it looks like the CPU is faulty .

Did you try both sticks of memory individualy ?
Click to expand...
I haven’t tried alternating the RAM. It’s worth a shot so I’ll try that next. Keep the suggestions coming.

I’m looking at getting a 12700k or replacement 13600k but if there’s a magic bullet of trouble shooting I haven’t done yet I would prefer that lol
 
It’s 4 long beeps though, each beep lasts about 2 seconds?

Too late for me now but I’ll try 2 sticks of ram and see what happens tomorrow, will post an update too

Been reading about Contact Frames for helping lower temps.

Wonder if uneven preasure is causing the CPU RAM pins to not make proper contact and if the Contact Frame would cure this? (hope that makes sense)

If this is the cause, does it point to a faulty CPU?

Do you mean the replacement CPU detainment thingy I have? You recon that could have killed the CPU?
