On SugarBay/MahoBay platfrom,system will hang when open GPU-Z utility. Below steps can duplicate this issue: 1.Boot to windows 7 with IGD, install newest intel chipset(188.8.131.529 ) and IGD driver(184.108.40.20698 ). 2.Boot to windows 7 again,can open GPU-Z normally. 3.Shutdown the system,connect discrete graphics replace IGD,install discrete graphics drvier and reboot. 4.Boot to windwos 7,can not open GPUZ utility and sometimes system will hang when open GPU-Z utility. 5.I have tried to remove the "Intel OpenCL(TM)1.1 support..." from the Control Panel \ Programs \ Programs and Feautures,it can open GPU-Z normally. Can you fix this issue in GPU-Z?
