I've had failure with the monitor blacking out and unable to regain control of the desktop and have had to shut down computer. The original card was removed by Dell and an HDMI to the cpu was used in order to use dual monitors.
The power supply then went out and was replaced. However, I am still experiencing the blackout failure on occasion., even without the graphics card. I want to buy a new graphics card that supports dual monitors, but am not sure this would resolve this strange problem.
Does anyone have any ideas? If my Windows 10 corrupted in some way? Motherboard problem?
Any suggestions appreciated.
