I recently bought a new motherboard, cpu fan, ram, and monitor for my brother because he wanted an upgrade plus his motherboard died. I have a Asus VE208T monitor and a AsRock B250M-HDV motherboard. I've been trying to download an os, but the monitor is stuck on only accepting a vga input, and I am trying to do a dvi-d input. Therefore, I've been unable to get to the bios and I can't install windows 7. I've tried to switch monitors, but the same things happened on a working monitor. I am pretty sure it isn't the gpu because it's fan is turning on. I also know that the dvi-d wire is working because it is brand new. I've tried to adjust the settings on the monitor to make it accept dvi-d, but it won't respond to anything I do. I also tried to use a vga cable, but again it says vga no signal. Overall, I am left with very few options atm. If someone could help that would be greatly appreciated.
