laptop crashed after letting a friend use it. who knows what he did but the hard drive fried. i installed a seagate 1tb hybrid as replacement for the factory one and installed the 8 gig ram upgrade. was unable to get anything from the old Drive whatsoever. So am having to reboot from scratch. It ran win 7 home premium x32 factory installed when i purchased so product key should work for x64 after reboot correct? Any suggestions on a secure site to download a x64 version of Win 7 home premium? And how about installing the drivers, is there a certain order in which to upload? Always had backups, factory windows discs, system recovery, etc discs before. Could use a little guidance to do things properly. Would greatly appreciate any good advice to do it myself after the quote i received to have it done.
