after playing about with it i found out it was his processor,he had to take is board out today to take back to the store and have it replaced due to bad onboard sound,and rather than wait for me to put it all back toghether for him he did it himself ,so now he cant use his new board has he has no cpu,if hed just waited 30 mins i would of done it but oh no he had to rush,and now he has to find £100 for another,
well i least i know what to look for if it happens again the only things that woudent work was fdd and grafixcard
