I would contact Dell Tech support to help you find the right part numbers for replacing them. All you will need for them is your Service Tag located on the computer case.

I am thinking of replacing the motherboard and pwr supply in my dell dimension 4550.<br />
I want to know what facts do I need to know about the motherboard and pwr supply to purchase new ones? and where to look - in the software or do I have to actually look at hard ware to find serial numbers or whatever i need?<br />
Thank you

how to replace motherboard and pwr supply- where to look?

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.
