So my story here guys i just really need help.

I had GTX 970, then I bought a ROG Strix GTX 1080 from a friend.
I removed my gtx 970 and put in the gtx 1080. The fans spins a bit and the LED on the gpu works fine.
The display is on, went to desktop and after 5 mins the display went off but the pc is still running.
I then restart my pc and it works fine again. then i played pubg for 5 mins or more with no issues.

A few minutes after playing, I uninstalled the gtx 970 driver restarted my pc to install the gtx 1080 driver , download 1080 driver the screen went off. After that i swapped it and put the gtx 970 works fine , put the gtx 1080 again now there is no display , and also the fans on the gpu are not even spinning and also no LED on the gpu at all , sorry for the long story , i just wanted to put as detail as possible ,what is causing it? Please help , much appreciated

Gtx 1080 rog strix
Psu cougar 80plus 500w
Cpu i7 6700k
16 gb of ram ( viper and teamgroup )
Wind 10

you need to include the model, and include it's overall time in use.

some of their units were rather low quality.
there's a good chance this one just can't put out the necessary power when under heavy use,
regardless of what it's stated wattage may be.
Thanks for the reply , i got it on amazon 2.5 years ago , and its CGR st-500

GTX 970 = 145W
GTX 1080 = 180W

Many GTX 970 used dual six pin if I recall. GTX 1080 reference card used 1 8-pin.

If your Cougar power supply doesn't have the required connectors, it really isn't suitable for running the card.

Technically only a 450W PSU on the 12V rail, and significantly more 5V and 3.3V then is needed in computers as new as 6th gen. That indicates it is an old group regulated design, not really suitable.

Thank u , it has 6+8pin connector the cougar one ,i also forgot to mention that i tried my other corsair psu cx600M with it and it went to desktop normal this is before after i swapped my gtx 970 , but now i wanted to give it a try and put the corsair cx600m and there is no display also? Did i break something , what would cause the issue? Is there something on bios or something like that , thanks in advance

BIOS update wouldn't hurt.
vBIOS update is more risky, but also a potential solution.

CX600m is a more competent unit, depending on its age. Though even the old green label one is likely a better unit then the Cougar.

It is possible the card has simply broken. Do you have another system to test with?

Make sure your power supply unit (PSU) is working
Press the Windows key + Ctrl + Shift + b to force a refresh of the video display/adapter.
Try using a different display cable or monitor

this is a fairly old card now.

it's possible that it just died on it's own
or even that a lower quality PSU caused damage.
Okay sorry for the confusion here , and thank you for your help , appreciate it , what i did ,here i did nothing basicslly i just turned off my pc maybe i clicked the pcie connector , but it was already in the gpu. , changed ram and it works? Gpu fans running normal , test it on furmarj for 10 mins everything is fine , played pubg for 30 mins everything works fine , i dont know what happened tho , even tho im getting fps drops abit maybe because its a driver issue? So should i be happy now and say the card is fine ? But i just wonder why all this happened ? And suddely works , also i tried on the psu corsair 600w not the 500w and it just works, i feel relief now but still hehe , what should i do next pls

Okay guys i want to buy a new psu but i also want to try the gpu if its good or not , or its just my psu is not handling it , i heard that you can use 2 psu in once and the gpu hooked on the other? It is really safe? Is it fine to do it manually ? I just want to test the gpu , but should i try it ? Thanks in advance

Yea sorry didnt update much about it , after 1 -2 hours of playing on the 500w psu the screen went off pc is still on , so i dont know as u guys mentioned its psu so thats why i suggest a 2 psu in one pc just for testing to see if the gpu the issue or psu , until i get a good psu

Update : so after getting a psu corsair cx750w turns out it was the gpu problem , we tested it on the furmark , and the gpu watt is playing , it goes 65w jump to 140w than goes down to 64 than jump , back and forth , i dont know what causing this but the gpu is faulty maybe , because when thus happen , the screen turns off ,my friend suggested a technican repair , because he said u can repair it , but i wonder if its worth repairing it , or it might break again or something

Are you monitoring temps on this GPU?
I couldnt really see much i was monitoring the watt , but like when we first booted it the gpu didnt turn on , no fans running tried several times until the fans turn on and gpu also than i on windows after 5 mins of booting on idle , no screen suddenly , restarted pc than went to furmark , and suddenly again screen turned off , the weird thing is here , i played on the gpu like 3 hours on my cougar psu 500w with no problem at all, a week ago than after thst screen went off , i honestly dont know what is happening ,

paying someone to fix this card, if it would even be possible, probably isn't worth the money.

if you're considering it, get an estimate first and see what they might b

They said its probably from 30 to 40$

did they mention what exactly they were supposed to be doing to "fix" this card?

giving you an estimate like that sounds like they have some idea of a simple repair.
or would they just be charging this for a initial diagnosis?
They really didnt mention it , they said it usually cost from 30$ to 40$ , didnt mention much , if its simple than i would prefer fixing it my self in general , i feel like the card is not faulty completely but there is an issue becuase i played alot of games with it , i dont know i might just send it to the techincan repair , no other choice?

these 1080 cards had a common problem on 12v rail i would also be interested in temps of the card and has it ever been overclocked or had its thermal paste changed.

True
i've never heard of a physical "repair" for any hardware being cheap, especially if you have to cover shipping.

most places will start with a diagnostic fee to access the system for a problem.
True , well they actually said we need to check it first , but most card we fixed , usually cost 30 to 40$ so im not sure about this

Interesting , i mean if i would do anything my self to change it , should i give it a try of changing thermal paste? But also im still like confused when i tested it on furmark yesterday , the watts jumping between 60w to 150 than 64w back and forth , is that might be the cause?
