Problem about my GTX1070ti driver clash on ubuntu 16.04

I have successful installed the latest GTX1070TI drvier on my ubuntu 16.04, the information of nvidia-smi is OK . But sometimes when I restart the ubuntu, I found the driver was crashed and system can not find the driver. I have to re-install the driver every time. Who can help me to solve this problem?
