display keeps going black randomly . mainly during heavy load like gaming . display comes again and goes black again . sometimes just pressing any key in keyboard or by moving the mouse the display goes black . monitor light remains on . and sometimes show power saving mode tried in safe mode , still the problem remains . strange thing is when I removed graphics card from mother board and boot up the pc everything runs fine no display issue . this is not a monitor or vga cable or graphics card issue as I checked my gpu and monitor with other system and they run fine . now my guess is , it is either motherboard issue or smps issue . I cant confirm . and ya all my drivers are up to date and reinstalling windows also did not fixed the problem . can anyone confirm what might causing this problem ?
