Does your old pc have an RGB output (most don't)

Does your new tv have an RGB Input? (Many don't)

Make and model numbers would help us help you.
Your PC probably has VGA output. If your TV doesn't have a VGA input it likely has component video input via 3 RCA plugs. This is not the same as RGB (unless your TV has a way to set the input to RGB). If your TV has a way to select RGB in one of the menus you just need a cable with vga at one end and 3 RCA plugs at the other.

If it doesn't you will need a converter

My computer has a standard 15 pin, (5 pins in 3 rows) pc connection. The tv has component red green blue connection, with a red and white audio below it. I've purchased a cable that connects the pc to tv but the Windows welcome screen is the only thing that appears when I turn it on. I think maybe I need to change some of the computer settings, as it recognises there is a desperate monitor attached but nothing appears? Greatly appreciate the help.

VGA is not the same as component video so unless you can set your PC to output YPbPr you will need a converter not just a cable.
