I bought a Shuttle SH55 and an intel I7 1156 to go with it Since the i7 chip doesnt have integrated graphics, I have to use a separate graphics card I'm using a GeForce GT240

I only have the video card and CPU in right now, nothing else (no ram, HDD, optical) I have a monitor plugged into the video card's D-Sub port.

When I turn on the PC, The video card fan and cooling fan for the cpu turns on, but I don't see anything on the screen (and yes, the screen is on) Any ideas why? Is it just not posting, or is it trying to use the integrated graphics?

edit: notes: USB ports aren't powering the keyboard / mouse

Most BIOS won't go beyond POST until you have the RAM plugged in.

Can you post more details ? Processor / RAM specifications / power supply details / full motherboard serial number? – Sathya Oct 21 '10 at 22:45
Intel i7-860, 1156 / G.Skill Ripjaws 4GB DDR3 1333 / Stock 300W shuttle power supply / SH55J motherboard / GeForce GT 240 – davidosomething Oct 21 '10 at 22:47
Your power supply might not be sufficient to power the GT 240. Can you disconnect the GT240 and use the onboard GPU ? – Sathya Oct 21 '10 at 22:55
nope, neither the i7 nor the motherboard have onboard GPU – davidosomething Oct 21 '10 at 23:08

The GT240 is just NOT compatible with the Shuttle SH55J motherboard.

Shuttle has a parts compatibility list here: further details on my blog:

I'm now using a compatible ATI Radeon 5770 (which requires 450W minimum, but is running fine on the 300W supply) I bought an SH55J compatible 500W power supply, too, which I will put in later just to be on the safe side.
