I'm sure this is a question that comes up here a lot. I just put together a home build (my first time doing so). Everything seems to be powering up fine: motherboard lights up, cpu heat sink fan and GPU fan as well as all the other fans are running fine, the DVD drive eject button is working, etc. But I can't get anything to show up on the monitor. I'm using an lcd tv as my screen, I've tried both HDMI-HDMI and VGA-VGA (although the graphics card doesn't have a VGA input, only DVI and HDMI, so I'm using a VGA-DVI adaptor). BIOS will not show up on the screen when it's supposed to.

Is this some basic problem with using an lcd tv as a monitor that I don't know about, or is there likely something not working right inside the computer hardware itself?

For reference, my build is:

Coolermaster 690 case
Gigabyte 890FXA-UD5
AMD Phenom II x4 955
Sapphire Radeon HD5770
Corsair 750tx power supply
Samsung 1TB HDD
4GB (2 x 2GB) G.SKILL DDR3 1600Mhz RAM
some cheapo DVD read/write drive

Thanks!

First tryout using a LCD Monitor (not TV). When you have everything working right, you can experiment with the TV as a monitor. If not, you are introducing too many variables, and this will make trouble-shooting more difficult.
