I called dell to resolve a problem with my xps 600 they said it was a hard drive failure. I bought a new one and tryd to reinstall the os (still got the same message) so i brought it into a computer repair store. They said it was my mother board however i can run full diagnostics on my hard drive etc. It just fails to boot im tottaly lost as to what it could be and if it is a mobo issue I can not aford to replace it with a dell mobo. Hopefully some one can help me.
