My Dell XPS One 2710 has a boot loop problem, first it’s the normal Dell Logo, then it turns into a grey screen with the command prompt ‘_’ and then it’s a black screen, then it goes back to the Dell logo screen and the process is infinite..

I ran the diagnostic from the f12 button, it said this exactly:

Error Code 2000-0142

Validation 112222

Msg: Hard drive 0 - S/N Z1E0H9FS, Short self test unsuccessful.

The given error code and message can be used by Dell Technical Support to help diagnose the problem.

Do you want to continue testing?”

then it’s yes, no and retry.. please help, what do I do??
