Try searching on the H.P download drivers and software page using "Evo D510c "as the model number.

If you are missing the audio driver try the Vista one for the dc7100.
There is no graphics driver for the d510 or d530's onboard graphics. They are not Vista or 7 capable. Buy a used Radeon 9600 128 MB AGP card or a GeForce 6200 128 MB AGP card and those will work fine with W7, and will be fine with the power supply.
You shouldn't be missing any other drivers.
