You will need to move data from the C: drive to one of you other drives. If you have movies/pictures that you don't really need on your main drive then it's easy to drag and drop them across to another drive.
Either that or you will need to buy a larger SSD for your C: drive and reinstall Windows or use cloning software.
Have no fear.... I battled this issue for months....Support assistant is the cause of this problem.,... Just uninstall support assistant.... It's buggy and causing this problemUpdating and installing drivers will fix the problem? i dont wanna take risk updating BIOS coz i dont know much about these stuff. Yesterday it crashed again and said Boot Faliure on device, did not reboot the whole day and this morning its fine again. usually after crashing it says scanning hardware issues but yestarday directly boot faliure.
