Hello guys, I just built my first computer(I hope) and I am experiencing a problem. I turn on my monitor it says acer etc etc, then turn on my computer, and it says no signal. All fans are running smoothly with no problem, but after about 45 seconds the gpu fan stops spinning. I have connected my dvi-d port into my motherboard and my vga into my motherboard as well. My monitor also has no place for an hdmi port. Could you guys please help me and I also have a problem with connecting a dvi-d cable to my gpu. There is this grey cover saying dvi-i on it in the grill plates and I can't seem to take it off too plug in my dvi-d in to. The main problem is the monitor saying no signal, all fans are running. Could you guys please tell me what could be going on.
