Laptop hoster will not re-install anymore

[NATHAN]

Hi ,you may recall me having all the trouble with my desktop not re-installing hoster ,which is all ok now. I have had to reload windows onto my laptop cause of massive error messages ,and now i have fixed windows my hoster will not re-install. Once again it thinks im useing a different comp (if only i could afford 2 laptops ,he he) ,it is a laptop everything is built in so there cannot be anything different on it except for a new wirless network card. Can you please reset the reg for my laptop. I tried to ghost the hardrive image before whipeing but it would not recognise my external hardrive.

many thanks nath.

p.s. sorry to be a pain agian.
only the second time i have ever had to format my laptop.
