Fans are running and you don't see anything on the screen. How do you "try to turn it off" then?
Can you get into the BIOS setup (by pressing del or esc or F2 or F10 or whatever your motherboard needs to do it)? If so set it to boot from CD or USB before booting from the hard disk. Then try to boot from any other bootable medium (such as a Linux disc or the Windows 10 recovery drive you made, or the Windows install disc or stick you can make for free) and see what happens. Does it work?
My computer recently just froze so I of course restarted it but when it restarted it turns on and the fans are running etc but nothing is showing up and when i try to turn it off it just wont turn off and I have to unplug it. It just wont stop doing it and I got it to work by some miracle yesterday and it was running perfectly fine and was running a huge game but later when I wasnt even in the game i was just checking my emails it shut off and continued the previous problem. I dont know what to do to make it boot up and actually work
