I bought a new HD 4670 AGP 8x videocard for my PC, and there was a problem, when i connected it 2 my motherboard, the videocard didnt give any signal to monitor and black screen all the time, couldnt see POST screen.
I have Intel 865GV motherboard.
400W PSU with 20A on +12V rail.

I have reinstalled Windows, reinstalled BIOS, upgraded BIOS, tried both VGA and DVI ports, nothing gets me out of black screen.

Welcome to TSF.

What's the make and model of that PSU? 400w and 20A is a bit low.
Also please include the rest of the specs.

Thanks

And yes, what the rest of the specs u need?
+ I heard the 4670 was a power efficent card, so it doesnt need that much power.

It's not a power hungry card, but your PSU, Which is so far nameless unless you can tell me what brand it is, doesn't have enough amperage on the +12V rail .You need something like 30A for that card and possibly a bit more wattage than 400.

the rest of the specs would be: Motherboard-CPU-RAM and the brand of that PSU.

You don't want a no name PSU to damage the new card I would assume?

That video card requires a minimum of 400w, so you should go above it a little bit.

Newegg.com - XFX Core Edition PRO550W (P1-550S-XXB9) 550W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply

This is a very good PSU and will have no problems handling that card.
