hi,
i have same problem. After patch blue screen (before patch launcher problem finally solved).
I test temperatures but i don´t see any problem:
First run gpuz for temperatures log.
Blue screen is with 90/91º celsius in my ring.
Then i stress graphic card with occt and with afterburner i up/down ventilators for check what happend with high temperature.
At 97º celcius, all clocks diminish its value automatically until reach 87º. Then clocks go up to 100% again.
No blue screen, no reboot.
I have the feeling that many have appeared blue screen right after i press a button or axis, or both, but this is very subjective 

.
i5 750, 4G ram, p55-ud5, xfi, asus 570, 1000w power, tir and x52.
