Just a quick one to let those who tried to help me in the past regarding the Disk read error and Boot disk failure on POST. It turned out that all along it was my monitor. I only found out when one morning it would not boot at all then while watching the restart the screen flashed on with the desktop, if I turned the monitor off and then on it worked for a second then went off. After connecting a new monitor all is 100%, even after a 3 day shutdown. So once again thanks and a Merry Xmas to you all.
