Ok, so the system i have is a
-amd ahtlon x2 dual core
-asus motherboard

I bought a powercolor hd 4870 1bg video card. I followed the instructions and deleted the onboard video drivers then went to my bios screen to make sure that my video output is set to PCI. Then i turned off my system and put in the new video card and everything fit in perfectly.

BUt, when i goto turn on my system the monitor does not work.....no picture is showing whatsoever....not even for a second. But, the computer is up and running and the video card fan is spinning.....so i know the video card is being powered to an extent.

I spent all night yesterday on google trying to figure out a solution and figure what im doing wrong.......but im not doing anything wrong!!!! I even tried installing the new cards drivers first then manually put in the video card and still does not work

The only thing i can think of is that my psu is only a 250watt and the video card requires 500watt. But, when i researched this on google there are many people claiming that a 250w psu can support a 500w video card....it might not be good for the system but it should work.....but i keep getting a blank screen.

any help is appreciated!!
 
Yes this is the typical issue for a GPU that needs power. My uncle JUST went through this after listening to Best Buy techs.

4870 1GB requires like a 500w PSU (found here) http://www.computerforum.com/90110-power-recommendations-video-card.html

Here is a great power supply that will handle it and give you a bit more.

Bit more power then you NEED but that is a good thing. Maxing your PSU 24/7 can lead to failure...and that means a chance you can fry your whole rig. 20-30 more for a PSU is worth it when you fry your 400-500 system ^-^

thanks for the response. I actaully just firgured it out and i feel like an idiot. i looked at the video card again and noticed 2x6pin connectors and my weak psu does not have those connectors
 
Yeah just make sure to buy a quality PSU...its a simple mistake till you learn it the hard way like the rest of us :)
