well its almost as black but i stil l see some stuff moving but very dark and when i re open the monitor it becomes brighter than usual and after a sec it turns black again
 
might be a monitor issue, hardware. if you have a laptop or another desktop, try using the monitor there. if it happens again, then it probably is a monitor issue.
or if you have other monitors, try it, if it happens again, then it's not a monitor issue

its your monitors backlight power supply/pc board that has given up.

I know because it is starting up, but cant sustain it. COuld be minor to repair, could be expensive.

if youd like take it in and get a quote to get repaired.
