Question DP TO vga not working! confused..

[RishabhfromIND]

Hey ya ! Here are my specs:
3GB ddr3 RAM, Pentium G620, and trying to install Dell AMD RADEON 7570.
So I have a pre built system by Dell which I bought in 2011, I decided to put a cheap GPu in it (it's brand new BTW but low cost) .
It has no VGA output , only DP or Dvi I dual link, So I inserted the GPU in pcie and joined the DP to VGA cable to it (3 cables I have tried) but all I see on my screen is A no VGA cable detected error. It works fine on integrated GPU.
I tried everything to make it work, but the computer won't boot due to no display.
I don't know what is causing the issue, is it the PSU or something else ?
PS: I have a Inspiron 620s with 255 Watt PSU.

Here is one more symptom, my moboe light is dimmer than usual but all my CPU fans including the GPU fan is running and I have tested the GPU on my friend's PC.

Does your monitor not have a button that can change between signals - vga, hdmi, dvi, etc.?

But you should just send that card back as your current psu isn't enough for it.
Recommended is at least 400w - granted, manufacturers exaggerate a little, for safety reasons, but that's still not going to make up for the more than 100w difference from your current psu.

No bro
People are running AMD 6670 on the same PC. AMD 6670 is recommended for inspiron 620s even though it needs 400w PSU.
Moreover, I have removed CD DVD drive reader and extrai fan.

What's your monitor? Can you go into its menu and change the video signal?

I have a Dell Analog IN1930 720p @59hz
No, I cant use the menu.

Troubleshooting the Dell IN1930
If this doesn't work, I'd chalk it down to either the psu, or the cable - were all three VGA to DP?

Going from display port to VGA you probably need an "active" converter like this https://www.amazon.com/DisplayPort-VGA-Adapter-Active-1080p/dp/B003V4TV8O.

Thanks. One more thing, Do I need an active converter even if I am using Dvi I (Analog) to VGA ?
It should not require more power since both are analog. ??
