5070 FE no signal

[ninjag]

I originally posted this in an older thread of mine, but thought it better to have its own thread and I can't delete the other one.

3 month old 5070 FE is suddenly showing no signal.

Monitor and cable work fine on another computer.
Fans are spinning.
Tried HDMI cable but no luck.
Tried removing and reseating but nothing.

I installed an older card so I could access the bios etc, but it isn't working either. Could this be the motherboard that's failed?

Cheers

That doesn't happen very often, but I guess it is possible.

Did you check the power connector is in good condition (graphics side and PSU side), no melted pins, etc? Though, that would not impact the older card, unless it used the same power connector, which I doubt.

Can you clear the CMOS? Don't do that if you have drive encryption enabled, or use Windows Hello.

Did anything happen recently? Do you move the PC? New USB drive?

When did this start? Were you using the PC, or just turning it on?

Thanks for the quick reply.

It was working fine last night, suddenly this evening it won't work.

I think the power cable is ok, the older card is a GTX so I'm using a spare 6+2 connector. Power is getting to this card as well.

I've pulled the battery and waiting as we speak. Only problem is that this motherboard needed a bios update from the beginning to be able to use the 5600X PSU and I can't remember if the screen will work. I remember having to use the special flash button at the back.

Getting pretty damn annoyed with this build. I can hear my son gaming away upstairs on my old rig which is still going strong. Maybe I should have stuck with intel.

 

[ninjag]

Removing the battery has made no difference. My monitor is doing some stupid burn test thing, but as soon as I plug in my son's computer it works, so it's not the monitor. I've got a second monitor I'm also testing with and I get no signal there either.

Could it be the pci-e slot has failed? Although I've tried the older card in the pci-e slot lower down as well and nothing.

 

[ninjag]

Monitor is definitely fine, I've just connected my laptop to it via hdmi.

I'm going to try and re flash the bios as I've found my usb stick with the firmware on it.

Was it turned off, or left on?

Clearing the CMOS should not change this, the BIOS will be the version you flashed. Reflashing the BIOS might be an option if nothing else works. A 5600X has no integrated graphics, so no picture will be visible without a graphics card.

Have you removed all USB devices and just running with the bare minimum?

What is the motherboard and PSU? Are they both new?

Computer gets switched off when not in use.

I've only got the mouse and keyboard connected re. USB.

The motherboard is the MSI Tomahawk X570 and the PSU is a Corsair RM750X. I think my build is about 4 years old.

I'm currently reflashing the BIOS (using my laptop now), it's taking a while. I've got the 5070 back in because the older card didn't work anyway.

Once complete, I think that board has debug LEDs, can you report what they say?

 

[ninjag]

The white light next to the big CPU power connector is now solid white, but nothing is happening. The computer hasn't restarted etc and fans are on full. The front power button now doesn't work, even if I hold it down for ages.

I'll try the power switch at the back, then try some starts and if it doesn't work I'll try reflashing. I know the USB is good because it's the same one that successfully flashed the BIOS a while back.

The debug LEDs are above the ATX 24 pin, there's four, the manual says which is which, but I think: CPU, DRAM, VGA, boot, from top to bottom.

Yep, that's the one I'll looking at. It was solid white on the top CPU one.

I'm currently doing another flash. I might try disconnecting the extra internal harddrives. Maybe I should try removing the CPU and reseating it as well.

 

[ninjag]

Something isn't right here. That's two flashes and the white flashing light next to the USB has gone out, but the MB isn't restarting itself. It's like it just gives up trying to flash.

There's another thread about the X570 Tomahawk not booting here on the forum and it was resolved by loosening cooler slightly.

Hi everyone, I hope you are all doing well. Or at least, better than I am. I have just built my PC today. it is: Ryzen 7 5800X MSI X570 Tomahawk WiFi Nvidia RTX 3060 Ti 32gb 8Pack DDR4 RAM Seasonic Focus PX-750 I haven't once managed to get it to connect to two different monitors on...

Thanks, I'll have a look. Although mine has been working for years, so seems strange if that were suddnely the issue?

Running out of options and starting to give up. A new motherboard will be a pain.

I've found my old 1050 Ti that runs directly from the MB, so I'm going to try that just to rule out PSU issues.

I'm not sure what happens when the flash completes, the instruction page I looked at doesn't say anything about what happens next after the light goes out. I'd expect the board to restart automatically, but it doesn't say so.

It could be as simple as: CPU light = on, CPU = dead.

I just looked up the debug lights, looks like it could be the CPU. I'll need to see if I've got any thermal paste left. Damn, this is not what I needed on a Friday night.

On the MSI MAG X570 Tomahawk, the EZ Debug LEDs (CPU, DRAM, VGA, BOOT) will stay lit on the problematic component during the boot process. A steady light for CPU suggests incorrect CPU seating, a bent CPU pin, or a missing CPU fan connection, requiring you to reseat the CPU, check the fan, and reset the CMOS.

 

[ninjag]

Glad I hung onto the boxes and spare stuff from the build as I've found the paste, cleaner and spreader. Fingers crossed.

 

[ninjag]

CPU and heatsink cleaned up, new paste on and reseated. Ran the bios firmware update again and this time the fans settled down a little and it restarted by itself.

The light is showing on the front power button as well which is promissing. The bios update light is still showing behind. Still no signal.

Here's the CPU, the pins all look good. I did a full check using the macro function on my camera phone. What I did notice is when I tried to take the mahoosive heatsink off it pull the CPU out wiith it. I should have twisted first, hopefully no damage done.

Just waiting now.

Yaaaaaaas. I'm typing this message on the big rig! Looks like the motherboard debugging was spot on, it was the CPU - although I'm not sure what. The heatsink is massive and although it's clamped down could it have got knocked and the movement caused an issue? At least it's forced me to repaste the CPU, so I'll take lemonade from this lemon of an evening.

Very grateful for your help, you steered me towards that CPU light which ended up being the solution. I really need to get a proper backup in place just in case I ever need to replace the MB.

Thanks again. Now where's that bottle of wine! lol

Nice, I'm glad you got it sorted! Have a good one.

Yeah, maybe it got knocked, who knows. I guess the screws and mounting can also shift. This type of boot issue is not uncommon on AM4, though as you noted earlier, that's more when building rather than 2 years later.
