GPU causing computer to crash while booting

[rudiboi]

Straight to the problem. My 770 would shut down the computer after ~1.5 hours of gaming and I had to let it cool off before starting the system again. However, lately the issue became even worse. When I start the computer the fans of the GPU start spinning faster and faster and before i can get to desktop screen my system shuts down. The card is REALLY hot. I tried changing the thermal compound, nothing changed. When I installed a different GPU everything went fine. Any ideas? Thank you in advance!

in gpus, the thermal compound must be spread through all the gpu die, don't use other methods like the line or cross.

if its not that or maybe dust, i cant think of a reason for it to be running too hot,

Try loading bios defaults, I had a similar problem with my 980-ti under liquid. I reset bios to defaults and temps dropped from 80°C idle to 27°C idle. I still have no idea what caused it.
