When i tried it in safemode it kept sticking at MUP.SYS and rebooting. So it was back to the drawing board. I decided I had got a little further with SP2 so using my trusty laptop I streamlined SP3 into my original XP pro disk using Nlite. Burnt the image to disc using IMGBURN and the rest as they say is history my cousin now has a working PC again once I have install the manufacturers drivers for sound, video etc.
All this so he can play football manager 2010.
Thanks again for your suggestions guys.
