So, my PC was working fine since last 3 months since i built it. I was working on some documents the other day and switched off my PC. Turned it back on momentarily since i had realized an edit was needed the document i was working on but the PC did not boot. I thought nothing of it at the time and tried again. Still no boot. Then i started to diagnose what happened. over the next two days, i verified my PSU was working, RAMs were fine and Mobo was good too, i removed the card and tried the DP port in the Mobo. and the PC booted. I was surprised, because i was not even playing any game when i last shut my pc down. so i tried to look over the cables, checked if they were proper. Checked out. Connected the card again. No boot. 
 
In conclusion:
The computer does not boot up when the GFX is inserted, it does boot up when i remove it from the motherboard and plug the DP in the motherboard output. It does boot up when it is inserted (DP port in Mobo) but the power cables are out basically Keeping the GFX inserted but removing the power cables from the GFX card, also boots the system. but plugging the power cables in the card, it does not boot.

tried all methods for checking the alternatives, like loose wiring, fitting in the slot correctly, cleaning the slot for any dust, no problem was found with any other issue.

PC was working fine when i switched it off, i was not playing any game or so, i was working on documents. I switched it off, then turned it back on moments later, since i had forgotten to add some lines to my document, and that's when it just would not boot.
 
Please help.

Well since i have recently moved here, i do not know anyone here that can help me with that, i am trying out things that i can work on on my own. i have a few work friends but they have laptops. i am thinking if a windows update might have caused this? does that happen?

Sounds like there's a short in the system somewhere. Whether it's the PCI-e slot or power supply is really the only places where it may reside. Can you try plugging in different PCIE connector cables from your power supply? Does the card kick on normally? Try the secondary PCI-e slot on the motherboard?

Yes sir. it did work absolutely fine. 
 
Yes, i did check for cabling when i came here. In fact i was using the computer for an hour when i turned it off. I tried to switch it on and then nothing happened.
 
I do not remember if while shutting down i saw windows getting updated or not. That's the reason why i think that if a windows update might cause this. 

So you can't even reach the post screen? If yes, it isn't a windows issue.

With the card plugged in.. it just won't boot.. psu makes a click sound the first time I try it.. I get no output on the screen whatsoever with the card plugged in and connected. If I remove it and connect the video cable to the mobo, it does boot

I see. Time to have the card checked at a local shop.

I have the exact same problem. THE EXACT SAME. I’m trying to plug an amd r9 390 to a secondary computer since I recently bought an rtx 2060 for my main. The secondary computer does not boot when the gpu is plugged into to the pci-e port and is connected to the power supply. Simply removing the psu cables, the pc boots and I get signal to the monitor from the onboard graphics card and it boots to windows just fine. I bought a brand new psu and still the same (A waste of $100) it did not fix it. Thing is that gpu has a BIOS switch on it that switches from UEFI to Legacy BIOS. When I press the switch, the only difference is that the pc now does a sound when I turn it on just like it’s supposed to do but still no signal to the display.

Did you end up solving your problem? My gpu was working absolutely fine on my main pc before I removed it so there’s no way it’s faulty. For the record I’m trying to use it on an older pc with a sandy bridge cpu (intel second generation) from 2011 don’t know if there’s any incompatibility, actually I doubt it.

Edit: I reset the bios to factory defaults, removed the motherboard’s battery, shorted the CMOS jumper and still nothing.

Edit 2: when I plug the older gpu ( Radeon hd6700) the secondary pc was using, it boots fine. However the r9 390 is a really power hungry gpu, requires 2 8-pins connectors as opposed to the Radeon gpu which has a single 6-pin connector. Is it possible the motherboard can’t handle that power hungry of a gpu? As I said I bought a new psu for that system, it had a Corsair 700w 80+ bronze psu from 2012 and I replaced it with a brand new Corsair 650w 80+ gold psu and like I said, I had no luck with that.

A Cheap Power Supply will and can cause this kind of problem.

Hi bcavnaugh & CoolGTX,
 
Agreed with you gentlemen. Your points are valid. Unfortunately they do not co-relate to my situation.
 
I am using an Antec 650W Gold certified PSU (Model: EA 650W :Earthwatts). It is semi modular. It was the only PSU my system ever saw, and IT WORKED Well for almost 4 months until when the PC stopped booting up due to reasons unbeknownst to me.
 
The PSU was tested on another PC. It booted up with a 1060 on that system. Then I installed in my system, same thing as before, no boot. Why would my PSU suddenly develop a "safety feature" when it worked flawlessly for 4 months straight. In order to prevent over currents, I also have a UPS or an Inverter as some may call it, which takes care of any voltage fluctuations and also has a battery which lasts 15-20 minutes in case of a power outage, which would rule out power spikes and fluctuations in voltage etc.
 
PCIe cable being bad from the factory is impossible. The PC has worked with the same cables for 4 months, the PSU also worked on another system with the same cables. I would not blame the PSU for anything at this time. It is checking all boxes. There are others who have actually purchased separate new PSUs only to face the same issue with a brand new PSU. I do not have an excess of Mr. Benjamin Franklin to afford that option.
 
PSU cables were never mis matched. In fact i have been dealing with the same PSU for this situation. I have not and do not intent to actually test out more issues that pertain to PSU's as i am nearing conclusion that the PSU is all OK due to the reasons mentioned above. 
 
I just don't understand as to why the PC would not boot when the GFX is plugged in. There are many with this same issue. I am dumbfounded and despite being an engineer i cannot even hypothesize what could possibly cause this. It would have exploded in my face and i would be stress free knowing that the explosion caused it to fail. But no. Nothing. Not even a smell that could be suspicious. All capacitors on the GFX look good. NO bulges, no bursts. What is this strange symptom for which there is no possible cause. I am thinking RMA is the only option now. The engineer in me wants to know, at least the reason. I am tearing my hair over it. Maybe, EVGA  may even replace it, but i am not sure if i will ever know why.

Why didn't you also try to test your card in the other system?

You have me worried as I'd hate to see it not being the PSU again if you have to drive hours to the nearest tech store. 

Are you able to test a new PSU by purchasing one or is that not possible?

Wait, what?! That's completely absurd but at this point I will give even this a go.
 
I have a DP port cable that I use with my GFX. Do you mean to say, use an HDMI, but do not connect it to either the card or the MOBO outputs and then the next step? it boots and then you connect it to the card?
 
Can you explain the steps in this process? maybe it would work for me, its so weird now I want to try it. :)

It would be much easier to make a video showing how it is but basically the only way to get the pc to boot is by disconnecting the hdmi cable from the monitor, booting the pc, waiting for the rgb on the keyboard and mouse to light up, connecting the cable back to the monitor and i get to windows. Otherwise if i leave the hdmi connected to the monitor when i boot the pc, nothing appears on the screen and the lights on the keyboard and mouse dont light up. I know, it's not just absurd, its otherworldly. I have a lot of experience with computers, its my passion in fact, yet i can't comprehend how this works. It's the only way to get the pc to boot with the gfx card installed.

Wow. This is mind boggling...wonder what might cause this then?? Bewildering! So as I understand, what you are doing is:
 
Keep the HDMI connected to the graphics card. But disconnected to the Monitor.
Boot the PC. (It boots, surprisingly.) Wait for the lights to turn on on the keyboard and mouse.
Connect the HDMI to the monitor.
Voila!?
 
Wierd! If you can send me a video, that would be great actually. Send it on [link=mailto:ayaan.pathan@gmail.com,]ayaan.pathan@gmail.com,[/link] if you could. I would love to see this magic happen. I am in office now, but I'll definitely give this a go once I am back home later today.
