No Sound after instaling new drivers

I was running win7 32 bit fine before with sound before insatlling the 64 bit version all fresh installs.
Now No Sound on Acer m1641 after instaling new drivers !!,
i have the realtek updated drivers that worked fine on the first install.
The ironic thing is that i have the 32 bit win 7 running fine on my hp notebook and it flies!

Do you know the model of the soundcard on the Acer m1641, as I can't find much information on that model.

Dell Photo printer driver

I Can't get the Dell Photo AIO 944 printer to work in windows 7. It's connected to a desktop and run fine with my wireless home network.
MY friend installed W7RC on her computer can see the computer but can't print to it.
Can you help me to find printer drivers for Dell Printer online.

Hello.In device manager Please right click the printer, select update driver -> manually browse to the driverstore on the Vista partitiuon and it should find and install the drivers from there.

On the other way, you can download correct version Vista drivers from mfr website and ringht click driver setup , select properties and run it in Compatibility mode for Vista.
