Blackscreen and GPU fans at 100%

[MartinK3]

I recently bought myself a 1080ti. The previous owner had had it for roughly 6 months.

When i fitted it in my pc, and the pc started up everything seemed fine. Once it got "properly connected (indicated with the resolutuon changing to 1080p) everything went wrong.

I get a blackscreen, and moments later the gpu fans go to 100%. Everytime i restart my pc i get the blackscreen within 15 seconds, and the fans ramp up. 

I tried solving this all day yesterday, with no luck.

I've tried almost everything i could find online, and were hoping someone here could help.

 

I have not changed the thermalpaste nor has the previous owner, when i touch the gpu it doesnt really feel overheating, and the card is barely 6 months old. The pc does not have this problem when i connect it to my previous 1060, and today i am taking the card to a friend of mine to see if the problem persists if we connect it to his pc.

Ive tried DDU and then downloading the specific, and newest Nvidia drivers. Ive changed which PCIe connectors i am using, and changed the location of the card.

If anyone has any info or tips i could try it would be much appreciated:) ill probably be going strong this for the next 12 hours and if it doesn't work it has to be defect or something.

You have a good power supply?

Any previous overclock/profile applied in MSI afterburner or something that could crash the card?

I have a 750cx corsair psu, which should be enough? I havent checked afterburner for profiles, but i havent made any, and i dont even have it installed yet.
