Windows 10: My pc screen dont connect to pc after windows update.

I tried changing HDMI cabel but it didn't work.I don't know if that's screen fault or pc fault.Whenever i found someone that had a problem like me, the answers said to download something but how am I supposed to download something when I can't see my screen.

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

PC Build Steps

1.1 - Ideally put optical in SATA 0, and SSD in SATA 1, this will cause the optical drive to be the default 1st boot option. You can change it manually if not, but I like it this way
2.infinity - yes, that's fine. if it's above 70 +/- 5 degrees, then it may just need a repaste/remount
