Ati radeon?

Hello, I recently aquired an Ati radeon 5770, but I can't seem to use it and I don't know the reason, my motherboard has a pci express x16 2.0 port, I don't know if is the motherboard itself or is it my power supply, the card turns on the fan spins and everything, the pc even seems to boot ( I get the boot beep from the MB speaker) but I get no video. I need to know if it's my motherboard is outdated or is the PSU or the card is done for, here's my system specs:

MB:Biostar a760g m2+ (info here: http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=394#spec )
RAM: Supertalent 4GB 1x4 DDR2 800MHz
CPU: AMD Phenom x3 8750 2.4GHz
PSU:Apparently is of a brand named Omega here's the wattage:
+3.3v:24A
+5v:26A
+12V1:14A
+12V2:15A
+5VSB:2.0A
-12v1:1.0A
the following is in the sticker in the psu
"3.3v and 5v output total 200W" "Total output:450w"

I have no other on board peripherals or hardware. Thank you in ahead and hope you can help me.

  1. Did you plug the monitor into the video card correctly?

    Sounds like the card is dead.
  2. I did.
  3. Try a different output on the card. Try the card in another computer that has a good power supply.
