Re: DRIVER NEEDED: Advent 5421 (Windows Vista)
Your notebook should have come with a backup/restore disk (unless it came to you via a shady source). If you don't have those disks, you basically have nothing but an expensive paper weight.
Advent is the in-store brand of PC World (and there is zero support from PC World). The 5421 is basically a rebadged Uniwill U50SI1 (you should see this printed on the underside of the laptop). I'm fairly certain this is the same as the [url="download.gericom.com/NOTEBOOK/Phantom-Serie/A4-Superlight-53120-U40si-U50si/"]Gericom Phantom A4 Superlight 53120[/url], the Gericom website contains drivers and a user manual.
