if i were you i would store all my kma's on an external hard drive and all my music plus any other things i saved on you karaoke computer, then reformat my hard drive, go and get all windows updates then go get my video card updates then install hoster.
i hate waiting !
plus theres nothing like a fresh computer ! its sooooooo much faster.
i reformat at least 2 times a year (cause im bored)
i like testing
