Hello
I recently installed a GTX 780 Ti on my system and since then whenever I open up a game my monitor shuts down after a while and shows a "No signal" icon. I still hear sounds and everything but I cant see anything

PSU should be more than enough I think since its 600W

Does anyone know what it can be?

The message means the software display drivers failed.

That could be because of
1) a bad driver install, but you've re-installed a million times
2) bad underlying software that is killing the video driver (e.g. bad dot net used to take out ATI drivers)
3) The Hardware card did something that messed up the driver. This is what happens when people overclock their GPUs to the point the gpu fails -- you get blue screens...

When you launch the game does it change the screen resolution / refresh rate to something your monitor cannot support ?

Suggest you go into setting for your game and update display to the lowest setting you can configure and see if suddenly it works. If so you can change to default and see if the game detects your monitor correctly and sets up video correctly.

Could also be driver problems that are triggered when a game flips into 3D mode. Uninstall you video drivers and load new ones from nvidia web site.

Post brand and model of your "600W" PSU. There are no label police for PSUs and many $30 PSU labeled 600w can't actually deliver 300.

No it doesnt change anything. It loads and as soon as I get in the main menu it just "shuts down"
I tried installing the newest drivers. The same thing happens.
I even tried to test the GPU with Funmark and the same thing happened :/
As soon as the monitor shuts down tho, I can hear a "disconnecting" sound (Just like when u disconnect a USB stick) and when I restart I get a message like "The gpu driver has failed. The basic driver is being used. Please check if there is a newer driver available"

The PSU is a EVGA 600W White.

Ohhhhhhh ""The gpu driver has failed. The basic driver is being used. Please check if there is a newer driver available""

Get a copy of EVGA Precision or MSI Afterburner or other overclocking software. This software is usually used to INCREASE performance (overclock), but you are going to use it to UNDERCLOCK the settings of your 780 Ti. Set the clocks and memory timing for your 780 Ti about 20% SLOWER than stock clocks.

Now test your PC again.

If it fails again at 20% underclock then
1. clean uninstall nvidia drivers
2. uninstall any "gaming experience" type software that might be adjusting driver settings.
3. reboot to load generic microsoft drivers
4. load latest nvidia drivers.

If it works at a 20% underclock then gradually work the clock speeds back up again until you find a speed that is stable, no "The gpu driver has failed." messages.

I've had problems before (with an HD7850) and have seen similar failures on forums where a vide card can no longer run at its factory set frequencies. Slowing it down can allow it to run.

Good Luck.

Assume card is out of warranty. If so then you don't have a lot of options. You can rule out software issues on your PC by trying the card in another PC. You can blindly buy another card.

Good luck.

I found out its the PSU... 600W still not enough for some reason... even if a calculator I tried online suggested 600W...

Post parts. It could well be the power supply. But 600W for a single card system is VERY rare.

You sig says i7-960 @ 3.2, that's 150w max
x58 mb is a power hog, 50 max including drives
your video card is 250W max at stock clocks http://www.tomshardware.co.uk/geforce-gtx-780-ti-review-benchmarks,review-32820-15.html
TOTAL system power for a gaming workload on 780ti is 372W here: https://www.anandtech.com/show/7492/the-geforce-gtx-780-ti-review/15, maybe 450W Max for the system in your sig if we assume everything hits peak at the same time

Any chance one of the power connections is not on correctly (loose?), not passing full current. If PSU is moduler check both ends. If PSU has multipkle 12v rails try using a different rail.

I bought an EVGA 750W psu (which means MORE than enough juice) but it still shuts down.
I read somewhere that the Amperes are maybe not enough. Is that possible?
As for the rails... it has 4 different ones (all are 20A each) and I have 2 of them connected right now.
The pc works fine while NOT gaming. But as soon as I open a game and I get to the main menu, it just shuts down.

Each of those 20A rails gives 240W, for a total of 480 available to the card. I think you proved it is not the PSU.

(wattage is roughly volts times amperes. 12v @20 amps = 240w, you have two 20amp rails = 480 watts. People saying "not enough 12v amps" are really saying "some old 400W PSU delivered most of their power on 3.3 and 5v, a modern PC takes almost all its power on 12V, so if a 400W PSU only had 10 amps of 12V then it only delivers 120W of 12V even though it is a 400W PSU".)

Assume you have tried various different games and they all behave that way. (If only one game then uninstall game and re-install. Bad software can cause a sudden, immediate PC fail)

You can run DXDIAG (google it, it's on your system, part of the Microsoft direct x package used by most PC games: https://support.microsoft.com/en-us/help/4028644/windows-open-and-run-dxdiagexe )

Assuming other games and dxdiag also fail then I think you've done everything you can do to prove the video card is bad.

DXDIAG shows my gpu and the drivers...
I got a notification after running a game and restarting (got the black screen) that said "The display drivers have failed. Instead microsoft basic drivers are being run"
What does that mean? Is it the gpu or the drivers?
Im so tired of not being to fix this problem....

The message means the software display drivers failed.

That could be because of
1) a bad driver install, but you've re-installed a million times
2) bad underlying software that is killing the video driver (e.g. bad dot net used to take out ATI drivers)
3) The Hardware card did something that messed up the driver. This is what happens when people overclock their GPUs to the point the gpu fails -- you get blue screens, blank screens and "display drivers have failed" messages. Your card seems to be doing something that kills the driver even when heavily Underclocked.

If you feel like trying some more steps:

You can rule out thing like bad software / corrupted software by removing your current hard drives, inserting some old spare drive, doing a bare-metal win10 install and seeing if the card now works.

You can go to the Nvidia site and download a very old driver and see if somehow the current driver does not work on your PC. Sometimes they break drivers for old cards when optimizing them for new cards.

You can ask a friend to run the card in their PC. If it works then the problem is in your PC's HW or SW.

But at this point I'd guess those next steps have small (not zero) chance of success. At some point you pull the plug and get a new card. The gtx 780 Ti is a very nice card, I'd double check the warranty length if you bought it new. Then pull the trigger on a new card.

Good luck.
