Dell Inspiron 15 5577 boots into blank screen after dell logo, works fine after force restart

I have this problem with my Inspiron 15 5577 where during system startup: - dell logo appears - the system shows a blank screen (ash color) with cursor visible (sometimes it happens after password entry) - I force shut down by holding the power button - I start the system again using the power button - system boots into system recovery and advanced boot menu type screen - I click "restart" on that screen - system boots normally It has started happening more frequently lately... before it used to go blank screen after password entry but nowadays it just goes blank after dell logo... I do not believe it to be a hardware problem but something is wrong. What I have found by some trials is that I have sleep on closing lid setup, and then when I shut down my pc most of the time I just close lid immediately and allow it to shut down in the background. but maybe the software runs into a problem because sleep coroutine or something fires up at the same time maybe..?? because since I have stopped closing my lid immediately, I don't think I have run into this problem. but still, waiting for it to shut down to close lid is just annoying. Is this really the problem? If it is, how to fix it? If not, then what is wrong with my laptop and what is the solution? Please help me. Thanks
