Problem- laptop will always shuts down without warning after logging in the windows but I can still use the f2 and f12 to check the diagnostics and bios during the start up session.

But it says no problem and I'm quite confused because I didn't change any hardware and always update to the latest version from dell website.

By the way, this problem is not that critical to me yet cuz every time I've tried starting it like 3-4 times, it won't suddenly shut down and seems like it fixed.

But, unfortunately the problem happens too on the second day, and I wish to fixed this problem before it becomes more critical until I cannot do my assignment.
