VGA No Signal

This Christmas, I assembled a computer and managed to get it to power on successfully. However, when I plug in my monitor, I get a VGA No Signal message, and afterwards, my monitor goes to sleep mode with the orange light. I tried switching the mode to DVI, but the same thing happened with a "DVI No Signal" Message.

I've made sure that the VGA and DVI cables are in properly on both ends, and that the screws are tightened. Also, I have a GTX 660 video card, and I'm not sure if anything is supposed to plug into that as far as the monitor goes. Any help?

Here's some relevant build components:

Power supply: Rosewill Stallion Series RD500-2DB 500W ATX12V Power Supply

RAM: Crucial Ballistix Sport 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)

GPU: EVGA SuperClocked 02G-P4-2662-KR GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card

Mobo: GIGABYTE GA-Z77-DS3H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Monitor: ASUS VW246H Glossy Black 24" 2ms(GTG) HDMI Widescreen LCD Monitor 300 cd/m2 ASCR 20000:1 (1000:1) Built-in Speakers

  1. Note: I just tried hooking the monitor up by VGA to my laptop, and it worked perfectly.
  2. If you have a video card then you're supposed to plug in the cable from the monitor to the card, not the motherboard output.
  3. Ok, thanks. I'll purchase an HDMI cable and try agaim

    That card has DVI, why not use your DVI cable from the card to the monitor?
