So i purchased a dell optilex 7010 MT which i upgraded by putting in a new 450watt power supply and purchased a rx 470 4g grapics card along with it. so i put every thing together and everything was working fine until one day my games kept crashing and so was some other apps as well. Then all of a sudden my pc just shut off so i clicked the power button and it turned on no blinks or sounds and fully powered on according to the power led BUT their was no signal at all to the monitor i tried different hdmi cables as well as a differnt monitor NOTHING so i plugged into the motherboard vga and still nothing. i unplugged the grapics card altogether it did not like it so i plugged it back in i checked the ram still nothing,.
