Black Screen While fan is running after bios update and sleep mode

[WaseemChanna]

there was an update named (cumulative update) asking for a restart to so i pressed the restart button and a white screen with with title something like bios update apeared with a loading bar. soon loading completed and my laptop restarted but when it restarted there was no display but o could hear the fan running on full speed. i pressed the power button for few seconds to shutdown, once the laptop went off i pressed the power button normally and the laptop started and i could also see the display. i was happy that my laptop is working fine but it happend again when i was watching youtube and i left my laptop for a few minutes and it went in sleep mode, then i pressed the power button to wake it up but it didnt. there was no display and the fan stared running. again i did the same thing (long press the power button then start normally) and it started working but yesterday again there was an update named cumulative update asking for a restart and when it restarted once again the same situation (no display and fan running) and again i did the same thing to make it work. right my laptop is working but every time it goes to sleep mode it or i give a restart for update, it goes the same and i dont know why. it all started with that camulative update i first described, before that i used to give it cumulative updates and it was all working there was no problem with sleep mode too.
