2 weeks ago before i went to sleep I installed the windows update before the PC shutdown, and after waking up the next day i press on the power button and the pc turns on with all the fans turning on(GPU,CPU and case fans) but there is no video output so i check my GPU its working and then so i try to restart my PC with the front case button maybe that's the problem but nothing happens.

Then i take it to a local warranty and they were supposed to fix it, when i received it i reassembled my PC and it worked perfectly fine for a whole week but the next day the problem persists.The PC doesn't work like before and still no luck with anything.

Note: Yes i did clear CMOS but still no post nothing

My PC specs are:

CPU:
Intel i3-6100 with stock cooler

GPU:
GIGABYTE Gtx 970 Windforce OverClock edition

Motherboard:
GIGABYTE H110-S2PH

RAM:
4 GB Kingston Fury 2666 MHZ
8 GB Team Elite 2400 MHZ

PSU:
Cooler Master Masterwatt 500


UPDATE: I have a friend who has mostly same components and I've tried everything from updating the bios to changing some components of the PC still no luck
