Hello, i have this ~8 monthes old pc , my pc automatically shuts down when i play any game, i tried cleaning it and doing full reformat but it didn't work, then i realized that my gpu is reaching 90-91c after a few seconds of opening the game (Assassin creed syndicate) and i was looking at temps using OpenHardwareMonitor, like a 2-3 seconds before the PC shatdown, all the GPU sections in OpenHardwareMonitor (voltages-clocks-temps-load) showed not available (showed this mark (-) )
Can you help? Thanks.

PC SPECS:
ASUS STRIX RX 480
INTEL I5-6500
ASUS H110M-K MOBO
8GB 2133MHz RAM
SEASONIC S12II 620W bronze

EDIT : Yesterday i did the same test but only watched CPU temps, they were ~55-65 as far as i remember but it was pretty average and good
 
Solution
Its a little hot for none overclocked. The temps arent faulty as mine is hitting mid 80's. Its getting there tho just try getting below 90c may help. Try reseating the card by pulling it out and put it back in. After getting the extra fan test the card using furmark benchmark. If furmark doesnt cause an issue then the GPU should be ok.

I have nothing overclocked, i tried blowing dust yesterday but im not too good with these stuff, but i probably blew out all the dust from GPU, will have to try again, but if that doesn't work, what should i do?

I'll try finding a solution asap, but one important question, would my GPU be faulty or its just too hot? (its ~50c in idle)
