- Olive screen, blue screen "DPC WATCHDOG VIOLATION"

Hello!

Computer Specifications:
CPU: Intel i7-6700K
GPU: Palit GTX 780
Motherboard: Asus z170 Pro Gaming
Ram: 8GB DDR3 RAM
Windows 10 Home on a 56GB SSD, the rest on a 1TB HDD
Power supply: Chieftec 700W (GPE-700S) (has a month)
Monitor connected via HDMI cable to the graphics card.

Yesterday during the game the computer got stuck, the screen turned faded blue, so I was forced to restart the system. After returning to the game, the same happened, but this time the screen was olive. A blue screen appeared with the message "DPC WATCHDOG VIOLATION". I started groping, reinstalling the graphics card drivers, installed their older version. Did not help. After one reset, the "American Megatrends" screen appeared with the information "Overclocking failed! Please enter Setup to re-configure your system". I never tweaked anything, in the BIOS everything is set by default. In the end, I couldn't even start the system. The computer stopped at startup. There was a blue flag above and a flying circle below, which only flashed for the first second. In addition, there are some weird white stripes on the screen all the time, also in the bios. In the end, I thought that the format that has long been put off is a good idea. After formatting, it was possible to enter the system, but during the system update the computer jams with a black screen and the blue screen "DPC WATCHDOG VIOLATION" appears again. After that, I cannot enter the system again, because it stutters at the same start time as before. These stripes are probably a problem with the lack of drivers for nvidia, but I can not install them, because during installation everything goes out.

I will be grateful for any help.

If it were a driver problem, the image would be normal in the BIOS.
Unfortunately, everything indicates GPU damage.

You can still try on bootable Linux to be sure.

If the stripes also appear in the BIOS, this may indicate problems with the graphics card. Remove the card from the computer and try to start the computer on the integrated card by connecting the monitor to the output on the motherboard.

On the integrated everything flashes. So there is no hope for my nvidia anymore?

Rather not ... if it displays artifacts even in a BIOS where the image is low resolution and freezes the system when installing drivers, it is rather a chapel. You can check in another computer with a powerful power supply because the card, however, consumes some power, but I'd rather not count on it.
Have you ever checked its temperature? Have you used this card for a long time? Do you know her story?

It is hard. Thank you for your help. I bought a new card somehow in 2013. Usually 78 degrees under load, sometimes reaching 80.

At these temperatures nothing should happen. Nothing tragic for the load.

There are still 2 options as already mentioned:
1.

If the effect is zero, then
