Thanks Andy, it seems to be loading okay again since I deleted the pagefile and reset it but it has left some bad sectors on the disk which can't be overwritten
.
I bought the computer from overclockers in Stoke, much easier than buying online, I can take it in if there is any problems I can't solve.
I will see how it goes and keep a check on the pagefile, the first signs of it not reading the card I will reset it.
