Hi.NymsiHi,
May we get the specs for your VivoBook?
Disk size is 930GB of which 161GB is used.Two questions: has it only just recently begun to start up slowly or has it always been this way? What size is the storage drive in the notebook?
Once I did tech support for a fellow that had a slow boot up and the pc wouldn't work after bootup. I turned out to be a virus so virulent that it would not allow me to restore the pc in any way or reformat the pc. I asked someone at this website and they gave me some information about a killdisk program which would wipe the hdd clean and allow reformat which it did. Anyway if you don't want to go through the agony of killdisk/reformat on a failing hdd, just do what Kshipper advises. SSD HDDs are cheap these days.The number one reason a PC is suddenly slow is a weak/failing hard drive, My fix is to backup data from the old drive and rebuild the OS on a fast SSD.
