One option is completing a fresh install of windows over the top, providing that you have backed up your data (If Any)
Thanks a lot combat wombat-Just managed to fix my desktop- what I did is used my laptop's recovery disk (which I didnt realise, I could) which is also Vista (tho it's a different version) my pavilion then allowed me to use "system recovery" and made the back up disks- now it all up and running again-tho' I had to forfeit the "Ultimate" version for the "Home premium"! But I am just happy that I have it working and in a good state again.
Thanks very much for taking the time and bother to help me with this problem-appreciate it!
