hi everybody i have a problem and need your help
 
first i noticed that this problem happen only when using a Gigabyte motherboard and others is ok

the problem is when no display is connected to the motherboard and windows and miner is running ok if the power go down and return the system boots and miner begins till it define the gpu in miner console then it pause and doesnot mine till i plug a display in the motherboard it resume mining without any problem
this is too wired because it means i need a display for every gigabyte motherboard
please advise
