Thank you all for your good advice and the links you provided for me you were all very helpful and gave me some new knowledge thanks again much apreciated


Answer
The first place is to research the hardware you have to make sure it is supported under Linux and specifically under the distribution you are interested in running. The simplest way is to get a "LiveCD" which lets you try Linux without modifying your existing operating system. While this method is slower since it works only from memory and CD, it lets you try the different distros until you find one you are comfortable with.

I highly recommend finding a book to help you learn Linux (either from a public library or purchased) since it will allow you to read along as you perform the various tasks without needing your computer to view online documents. This is especially helpful during the installation steps.

Printers from major brands (HP, Epson, etc) have good support under Linux (http://linuxprinting.org)

Scanners are hit and miss, although a new scanner is cheaper than an upgrade of Windows these days.

Just about all video cards are supported using a fallback driver (vesa.) 3d acceleration is available for major cards such as Nvidia and ATI using the proprietary drivers from those manufacturer's websites.
