Can you see anything when your computer boots? Like the BIOS load? If not check your cables and make sure the monitor is on. If those things look ok reseat your video card.
If you can see the boot prompt for the install you can specify a resolution using the kernel parameters. At the boot prompt you would type "linux vga=ask". If you are still stumped please ask.
