Installed new graphics card, now pc won't turn on...
Ok...need some advice.
Just installed a new BFG GeForce 6600 GT AGP card into a Dell Dimension 4550 (1gb RAM) with an upgraded psu to Silencer - 410 Dell-2 (410 watts).
As soon as I put in the card, the system would not turn on. I saw green lights on mb and inputs in back of machine were lit, but that's it. Hard drive was not spinning. It was drawing power, but it would not start up (no boot). Also, the videocard fan was not moving so no power to the card, even though I did connect a 4 pin connector (tried 2 of them).
When I took card out and reinstalled previous card, system came on and booted no problem.
Anyone have any ideas? is there a way to verify what your psu is running at? Should be 410 but if it is under 350, I don't think this card will waork. But the machine should still be able to boot up, no?
What am I missing here?
Thanks for any help!
