eee pc 901 - drivers for web cam and wifi  

Hi kicker10 and welcome to the Forum. easiest way is to go to the manufacturer of you webcam and look for Windows 7 drivers there. Though if a suitable driver was no found automatically it could be that your webcam is not compatible with Win 7. If you can't find a driver post the webcam and any other hardware details here and one of us will look them up for you!
EDIT
Just had a look at the spec for your notebook. Did you run Windows 7 Upgrade Advisor before installing Win?

Mitch has given good advice. I have this information for other purposes, so I will pass it on.
Here are detailed instructions:

How to Find Drivers
search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone - will help you search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- - if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
