Yes, go the manufactures webite to get the Windows 7 drivers. As you were running Vista, I'll bet they have them.
Look in Device Manager to which device you need drivers for: Start/Computer-Right Click/Manage/choose "Device Manager" in the Computer Management table. Any device with Yellow "!" are the ones not installed.
I can't believe WIndows 7 wouldn't have all your drivers, as you had Vista, but then again, it is a laptop, so I don't know.
Try doing a "Windows Update" and see if that gets them. If you have network/internet working.
