ASRock P4S55FX SATA mainboard problems

i have an ASRock P4S55FX+ SATA motherboard, but no video output comes out! i have tried using a Matrox video output card, but no luck. what’s wrong with it? i have read the manual through and through, but still it doesn’t work. it has:

-pentium 4 cpu
-Macron power MPT-301 300w psu
-msi 52x32x52x cd/rw drive
-no hard drive
-no floppy drive
-no agp video card
-matrox video output card
-amibios bios
-case from otv electronics(i think)
-cooler master case fan
-no ram

i checked all of the connections and jumpers, but nothing appears on screen!

please help
