Hi. I'm experiencing some weird troubles using prema mod: I just recieved GTX980M card (Clevo) and i'm trying to install it into my P170EM laptop. So, i flashed my BIOS and EC with prema's versions, flashed vBIOS and updated drivers. And this card worked for me for some time, like half an hour or so, but after that my laptop started beeping like it's overheating, blinking keyboard lights included in that process, right after that my laptop shutdowned itself. Now, whenever i try to turn it back on it starts that "overheating alarm" procedure almost right after BIOS loads up and it shuts down right after windows loads. I tried my old card, and it worked fine. I assumed that this can be related to weak cooling system or something like that but at the moment of shutdown laptop emits no heat even with removed cover. Any ideas?
EDIT: According to GPU-Z stats, first shutdown happened when the card hit 90 degrees mark, but it was operating on 45 degrees for the whole time. (So it's not a steady buildup of heat, but rather a surge, like 40 degrees in 20-25 seconds after almost hour of steady performance on 45-60 degrees.)
EDIT2: I made it to device manager, using safe mode. And for some reason installed card does not appear in device manager at all. Does that mean that the card is fried? That would be a real shame since i followed every single piece of instructions.
