Acer aspire one netbook unable to start

[Appleoverwindows]

Today, I used it without any problems and decided to take a break from it so I just put the screen down for a little bit. Next thing I know, after about a half hour it starts making beeping sounds, a white bar is running down my screen which takes up 1/3 of my screen and it's saying it was unable to start.

When system restore came up, a pop up comes up saying x:\windows\system32\diskpart.exe is not a valud Win32 application but after a few minutes it fixed itself, I could log in and use it. I decided to shut it down and restarted it to see if it would happen again and it did. After it turned on, a blue screen came up and it went back to system restore, the same pop up saying x:\windows\system32\diskpart.exe is not a valud Win32 application came up and then it fixed itself.

Every time it fixes itself and I turn it off, it repeats itself over and over. Do anyone know what the problem could be???

Do you have your Windows installation disk? If so you could do a repair install.
