Have a PDC 640 10 years old and need a driver for my DELL cumputer with Windows 7 Premium

you might just need to reinstall he printer drivers

Drivers can be found here:

You probably need the Network & Chipset drivers, but make sure you get the right ones for your model.

Dell site offers Vista. You may get it run in compatibility mode.

This model was released in the Vista era but is not horribly old. I have updated some hardware from XP/Vista to W7.
However Dell does not list W7 as this model predates the OS.

However, microsoft lets you run compatibility tests with the Windows 7 Upgrade Advisor. See: http://www.microsoft.com/en-us/download/details.aspx?id=20

I would estimate your chances of success as very good - but check the MS Advisor.

You will have to download ISO image of Windows 7 Home Premium, 64bits, burn it to a cd, then boot from cd to get to the repair mode.

go to one of those computer stores they will tell you

In the Manufacturers website. It doesnt say it is compatible with Windows 7 or Vista. They have just mentioned XP as compatible OS. But try installing the driver from the following link

You will have to uninstall all the old drivers first as the pc will use those first then re install new driveres from dell
