...and you asked Dell about updating that laptop? ..and checked the bios? ..and checked Dells user forum for similar problems? Changing the OS in a laptop (and there is a LAPTOP forum here with similar posts..where this should be posted) at best is iffy. Some laptops cannot be changed to the Windows ate OS...did you check first? get everything you need at Dell...generic drivers are all AMD offers..and they don't work in every laptop.
