[SOLVED] Computer Boots Without Graphics Card - GTX 1080

[alyan_saleem]

Hello,

I have installed my EVGA GeForce GTX 1080 into my motherboard and have connected it to a CIT Active 85 500W PSU. When I boot my PC and have the HDMI in the GPU, nothing appears on screen but if I connect it to the PC HDMI, the PC works as usual. There is no sign that the GPU is working whatsoever as the fans don't spin at all but the rest of the computer is functional. The GPU is connected to the PSU via a 6+2 cable.

I have 3 other overclocked GTX 1080's which all require 2 leads, 6+2 pin & 6 pin, when the PSU only has 1x 6+2 pin which would probably explain why the overclocked GPU's aren't working, right?

Yes the PSU is obviously functional as the PC does turn on.

Yes the GPU is definitely connected properly to the motherboard.

And yes the PCIE slot is functional as when I plug in a GTX 1060, it works.

Any ideas as to what the problem might be?

Thanks in advance,
Alyan

The graphics source may be set to force the use of the integrated graphics in the BIOS.

Or the motherboard isn't detecting the graphics card.

 

[terry4536]

Try installing the GPU IN a different PCI Express x 16 slot. Try the graphics card in another system.

The problem GTX 1080 may be defective. It may have an electrical fault that trips the PSU to turn off.

There are no other slots.

It is a Dell Vostro 260.

The rest of the PC works, meaning the PSU is working. Are you saying a potential fault is causing the PSU to not supply power to the GPU only?

Or the motherboard isn't detecting the graphics card.

Without making any changes to the BIOS, plugging in a GTX 1060 works.

Then move another graphics card to that slot. And then install the problematic GPU in it's place. See if the problem remains with that PCI expansion slot.

Sorry for the confusion but the motherboard only has 1 slot. So when I install the 1060, it works and then when I replace it with the 1080, it doesn't. They were both connected to the exact same slot.

Then that is evidence that the problematic graphics card is indeed defective.

From your post I though you had a multi GPU system. Mining rigs are like that.

Could it be a problem with the PSU?

Ehh - how bout you let a friend install the 1080 in their rig and test. I’m bettings it’s that dumpster fire starting PSU - has just enough to power a 1060, not enough for a 1080.

It depends. The GPU may work normally until it needs the extra power at which time it probably crash. The other possibility is that the GPU detects that the PCIE cable isn't installed and doesn't work at all.

So it is possible to temporarily run an overclocked GTX 1080 with just 1x 6+2 lead until it requires extra power? Does my PSU (CiT Active 85) supply enough power even for a normal GTX 1080. It certainly does for a GTX 1060...

Is that for definite? Definitely because the PSU isn't supplying enough power to the GPU specifically?

 

[alyan_saleem]

From what I have gathered, the problem is one of the following:

GPU Defective
Not enough power supplied from the PSU to the GTX 1080

I could eliminate the chance of it being the 2nd problem by testing it with a different PSU, after which if it still doesn't work, it must be a faulty GPU.

That's probably about it, right? Can't really be anything else...

Question from 3hibajanoo3 : "i3 2120 with GTX 1080"

Hi. I have an i3 2120 system. Dell Vostro 260 (not 260s).For some reason, when I plug in my gtx 1080 (It's only to test if the gpu is working) I don't get anything at all. This is the case for all of my 1080s, I have 4 of them. All have 8 pin or 8+6 pin. My 6 pin gtx 1060 works though

Perhaps the PSU isn't powerful enough. What is it?

Try it in Safe Mode (F8) this is w/o GPU drivers loaded.

A lot of older motherboards require BIOS updates to support modern GPU’s

An i3 Dell will have a UEFI Bios and may need settings changed to run a Legacy video card. (not all new cards are UEFI).

It's a CiT 500w active 85 psu

Can you send me a guide for this or a link to the updated bios driver

Where do I find my bios update

Dell Support. Just download and install in Windows

I think there's a chance that might be it because it's right on the spec....and I'm not saying CIT sucks but I've never heard of it.....so automatically I'm leery of it.

I dont' know how handy with a voltmeter you are but if it were me I would be checking PSU voltages. You can google this.

It's a 80 PLUS bronze, so I doubt that. Currently i am downgrading from win10 to win7 to see if it's got anything to do with that

Can someone please kindly check if the CiT 500W Active 85 has enough power to power a GTX 1080.

 

[J_E_D_70]

You dont know a single human that can test your 1080 in their rig? If your 1060 works in your pc, and the 1080 works in another pc, its the psu.

 

[terry4536]

Can someone please kindly check if the CiT 500W Active 85 has enough power to power a GTX 1080.

The GTX 1080 has a system requirement of 500 watts. But I've never heard of that power supply, and that says something about the PSU quality (I've been doing this for quite a while).

But CiT 500W (from your description) should power the GTX1080.

Alright. I'll look into buying a new PSU soon.

Thanks everyone for their help.

Question from alyan_saleem : "Asus Strix GTX 1080 No HDMI Output But Fan Spinning & LED's On"

Hello,

I have an Asus Strix GTX 1080 GPU and when the PC is turned on, the fans are spinning and it is slowly blinking orange but when I connect a HDMI, there is no output on the screen but when I connect the HDMI to the motherboard and restart the computer, there is an output. There is no indication of the GPU being detected in device manager either.

complete specs? new build? did it ever work?

Question from 3hibajanoo3 : "GTX 1080 not working."

Hi, I have a dell MIH61R MB 10097-1 with an I3-2120. My 1080 asus strix gpu's rgb work (Powered by the pcie slot), but seems like no psu energy is detected as system directly boots into my integrated gpu. Could it be that my mobo doesnt support 8+6pin 1080s, as my 6 pin 1060 worked fine, what i think this is for is for energy overflow but i just dont know. Or something with my CPU being i3 2120 and not really meant to be with a 1080 hence pcie lane shortages etc. It's not a psu issue, ive used 3 psus so far to test this, or OS issue/Driver, tried multiple again. All it can be in my eyes is hardware support
Any suggestions will be appreciated! But I am no longer wanting to spend more money for testing.
