Boot/start-up is very very slow...AMD Mobile Semperon logo displays for ages, as tho the whole device has frozen...this finally goes, if you're patient enough, and then its attention turns to the CD drive...either it claims there is no drive, or there's no bootable CD in the drive...if I'm lucky, it eventually continues until Windows starts...usually successfully, but not always. 'anybody come across this before...it'd be handy to get some insights before heading down the route to "total reload"...thanks in advance. DH
