Hi Blencogo,
Many thank for your help and advice, I was told the same thing by a nabough of mine after i had an engineer in to look at it, he took it away and after two week's brought it back to me saying that it needed a new motherboard,
this after they had tried a new HDMI board in the computer, he never mentioned a power board problem, don't think he had any idear what was wrong with it, which also go's to show that we should all be carefull who we use to fix our computers as the total bill came to £250.00 an no workng computer.
Will order a new power board today and have it fited,
Many Thanks Again Blencogo
Keith
