After blood sweat and tears, got a reply from another forum which said 'I had this problem, its basically because the cd is for XP not Vista, with me the cd boot image appeared and then froze in vista and worked fine in xp.
You need to go onto the mobo manufacturer’s website and download the vista 32bit or 64bit drivers for your mobo, the drivers you need are
- chipset drivers
- Audio drivers
- LAN drivers
Then just install vista and install each driver in the order listed, one at a time restarting the comp after each one installs (if it doesn’t prompt you to)'
So I did this and it worked!
Now the next will be to add extra memory, put in an Asus EN7600GS Silent video card and maybe upgrade the power supply. I will then try to sort out Firefox which (it is said) is not compatible with Vista.
