When I connect my monitor http://www.newegg.com/Product/Product.aspx?Item=N82E168... with my graphics card http://www.newegg.com/Product/Product.aspx?Item=N82E168... with a DVI cable, no signal seems to go through.

However, when I use the same cable and connect it my motherboard (http://www.newegg.com/Product/Product.aspx?Item=N82E168...), everything seems fine.

I've disabled my motherboard's onboard graphics before connecting to my graphics card, by following these instructions: http://techtips.salon.com/disable-built-in-vga-card-msi...

I've also tried installing the graphics card's drivers, which came in a CD, before connection, but it didn't seem to make a difference.

Some photos below, if it helps.

And you hooked up external power to the new card?

Did a quick fix on the links.

External power to the new card? Don't you just plug the graphics card into the motherboard? Sorry, it's my first time building a PC ;_;

Here's the current setup:

Your card needs 1 x 6pin PCIe power directly from the PSU. The connector is in the back of the card.

I'm not familiar with that particular card but you'll need to connect it to your PSU as wel or it won't have the power to operate. Just plugging it into the Motherboard won't work. When you switch on your computer, do the fans on the graphics card work? If not, then you have not connected the power correctly.

Your internal pictures show that there is no 75Watt 6-pin PCI Express supplementary power connector connected from the power supply unit to the graphics card.

Yep. That was definitely the problem and it's been fixed now. Thanks so much guys! :love: 

It also seems I forgot to connect the fan at the back, so I'll go fix that as well.

By the way, what's the recommended software for benchmarking? And what or some other obligatory things to do on a new PC?

Some say Prime95 for stability test. Benchmarking would be more getting fraps to count your fps in different games.
