Default Computer Starts up, monitor won't turn on.

I just built my first PC and put it together, I believe everything is connected correctly as I followed the manuals.

The computer turns on, all fans are going, powersupply, graphics card, optical drive, hard drive, they are all running. I connected my monitor to with the blue monitor cables but the monitor light just keeps blinking meaning its in stand-by mode. I have a usb keuyboard connected, the keyboard was turned on for a bit because the keys light up, then when i pressed keys nothing happened on the monitor. Now the keyboard doesnt go on.

I also dont have anything plugged into the back of my graphics card, I dont know what those two red connectors do.

Any ideas?

Do you have your monitor PLUGGED into the graphics card?? There are 2 DVI ports, 1 hdmi and 1 DisplayPort

Do you have the 2 x 6pin power cords attached?

No i don't have my monitor plugged into the graphics card, because i dont have anything that will connect to those 2 DVI ports on the back of the graphics card.

And yes, I have the two 6 pin cords attached to the graphics card. The fan is also spinning on the graphics card.

I think i may need a better monitor? I planned on purchasing one with this build, haven't done it yet tho.

Alright just found a connector to convert DVI to my regular blue monitor connector... and i now have screen on my monitor.

You need the DVI to AGP converter.



It is provided with your graphic card.

That is why the monitor is not detected. When installing a dedicated card, as you, your onboard video will be switched to your card.
