New Comp Won't Display on Monitor

Asus P7p55d motherboard
November 9, 2009 at 20:10:50
Specs: Windows Vista
I just built a new computer. When i start up,
everything comes to life, there are lights on on
the mobo, graphics card, and all fans are
working, yet nothing will display on my
monitor. I tried several different cables and
also a different monitor. This monitor works
fine though, i use it with my laptop.
What do part of computer do you think it is most likely? obviously i would lean towards video card but i have no idea where to go from here.

asus Mobo
core i5
4 gb ddr3
HIS radeon hd 4890 turb 1gb
750gb hdd

Apparently you didn't benchtest your hardware before installing it in the case? And I don't see the power supply on your spec list? Do you get a single beep at startup? Any beeps at all?

sorry forgot about psu. 630 watt.
and no i didnt benchtest before building. first time building, i
probably should have done that. ive been trying to narrow down
the faulty part. i dont have an incase speaker, and i dont think
mobo beeps work with external speaker?

just for some more information:
when i start it, the gpu fan is spinning, there is a green LED lit on
the mobo next to "boot_device_LED" and a red LED lit on mobo
next to "cpu_LED"
there are also 3 red lights on the gpu

"sorry forgot about psu. 630 watt"

Wattage isn't as important as quality of the PSU & the amperage specs, plus you need to have all the required plugs. A decent 630W unit costs about $75 & for your system, you need one with an 8-pin ATX12V/EPS12V plug...that connection is what powers the CPU. Is your PSU compatible the Core i5/i7?

"i dont have an incase speaker"

Why doesn't your case have an internal speaker? You need to hear the beep codes (or lack of). Get a speaker. Here's an example:

"no i didnt benchtest before building"

Gut the case & benchtest your hardware.
