i thank you for your help it was much appreciated but someone at work told me to test the ram sticks i did this and after removing the stick closest to the h/s and replacing it with the other one it works again , to you this may seem obvious im not sure but i honestly had no idea this was/could be the problem
again thanx for taking the time to help and i apologise for any wasted time
mike.
