but i cant get back to undo it unless i press the restart button
this happens on both my screens (dual screens )
so i wondering if any1 knows why and how to solve it this happens randomly after a hour after reboot or while playing a game/browsing
i tryed to update gfx driver and cleaned the cooler on the gfx card i thought it was that but nope still have it also look at the airflow in the case but it looks ok and changed the power saving thingie to never for screen and HDD
also the temp for cpu is als normal 4*C (stressed)

Weird, graphics drivers updated? Cables in the back properly?
Answer #4
ye updated the gfx drivers . rechecked all cables even put in a extra fan but still dunno what be the problem
Answer #5
Well its not dodgy monitors as they both do it, and I don’t think it would be a hardware error either.
When it next happens, try pulling out the monitor cables and putting them back in.
