network driver

i have just installed windows 7 professional and now ethernet controller, SM Bus controller and PCI simple communications controller are not running.

Have you tried installing the chipset drivers from the manufacture's website?

No system specs listed so can't find them for you.

i have no internect connection on that computer and am using a backup computer for internet access.
i have tried locationg drivers under old files but no joy. i was hoping to locate drivers using this computer and then installing them but am not sure if that will work

A USB flash drive comes in handy for that but you could use a blank CD.

Windows 7 is usually pretty good about installing what you need but sometimes it needs a little help.
