building my first computer, monitor is blank

Here is my setup:
epox 8k7a motherboard
amd duron 750
crucial pc2100 ddr 256 mb ram
maxtor 7200rpm 20 gig harddrive
viper 770 agp video card
mitsumi cd-rom and floppy

My problem is that when I power up the computer nothing comes up on the monitor. From the color of the light on the monitor it appears to be in standby. The fans on the motherboard and the video card are running so everything seems to be getting power. I have also tried using a voodoo 3 2000 pci card but with the same results as the agp card. I know the monitor and the voodoo card work because I have them on another system. My other computer doesn't have an agp slot to check the viper card. Does anyone have any ideas or suggestions? Thanks.
 
This symptom is almost always one or both of two things: 1- Memory not seated properly. 2- Video card not seated properly. Usually no. 2 because most people aren't familiar with how an AGP card should feel when it's seated properly. There are TWO layers of contacts, so you should feel the two levels of meshing.
. Rarely it could be the CPU improperly seated. Finally, some motherboards are shipped with the CMOS battery disabled by jumper. Make sure the CMOS is enabled and clear it just to be thorough.

I noticed on the power supply that it says 230v. My other computer's power supply says 115v. Could this be the cause of the problem? If so, how do you change the power supply from 230v to 115v?
 
definately the power then....the little red tab thing that is either to the left or right of your 230V printing will allow you to switch it. Use your fingernail or a screw driver and switch it. I doubt you fried anything cuz you didn't really plug your PS into a 230V socket, although I don't know how the PS changes the current to a different amperage which has a higher potential of killing MB components. If your system still doesn't post, make sure if you have any FSB jumpers on your MB that they are set to the correct FSB and clear the CMOS just in case. Also you can check on the RAM and AGP like Zepper said.
