Thanks both and yes you are right, the problem is though I have a vaio VGC V2S desktop and Sony won't give out the instructions on how to open it up so I have to take it to a teccy and at £40 per hr plus vat. Still no use if it doesn't work. I will mark this as resolved. Thanks again and a Happy New Year.
