I need a new driver for my soyo monitor

Your soyo monitor doesn't require a driver. Make sure you download and install the latest driver for your video card and during the install of that, your monitor should have its drivers installed as well. At that point you'll be able to use your monitor properly. There isn't any drivers available on the net that I could find. Only other option is if your monitor came with a cd, that might have drivers on it.

P4X400 motherboard bad are there any replacement boards avalable?

Any motherboard with the same FSB speed and a Socket 478 should do.

Check out eBay:

Unfortunately the Soyo P4X400 seems to have a FSB quite long in the tooth: from 100 to 133 MHz.

You might be forced to upgrade the onboard RAM.

Wires for USB go to which MoBo pins?

there is two sets of 4 pin on each with an xtra ground you may not use.
Here is the link for your motherboard manual which shows the connections.
i.e you can connect your two sets of 4 wires to usb 1 or split them i.e 1 set of 4 on usb 1 and 1 set of 4 on usb 2.
