May just be a hardware issue and there is nothing you can do... unless it's under warranty.


I would suggest try loading a new OS from scratch in lieu of the data wipe you did. But I wouldn't put too much hope in that fixing your issue.

what is mean of "OS from scratch in lieu"?

what is price of new hardwere?? please say me.
