(solved) 2nd Monitor (HDMI) black screen, still detected by windows.

Hello there, today when booting my PC i encountered a strange problem. I run dual monitors, one is a ASUS vg248qe which i connect to my PC using DP. The other is an old 22" Digitrex TV which is connected via a VGA cable with a HDMI Adapter. Today my 2nd monitor is only showing a black screen & the only way i can turn it off is by yanking the power out the mains. The power button at the front is unresponsive. This has happened before but has been fixed by simply pulling cables out/in. Does anyone have any ideas?

My PC Specs are as follows:
i5 5470
GTX 1070
8gb ram
1TB HDD

It ended up working again after i pulled the power out & back in with the HDMI out the back of my GPU, & the putting the HDMI in.
