Please allow one more suggestion. At this point, the OP needs to use whatever resources are available to him. Instead of spending any more time on this. He ought to contact the manufacturer of his personal computer and provide them with a simplified explanation of what happened.
Although it is possible that the OP may have inflicted some harm to his computer, that is not known for sure. In fact, what the OP did was
not really an unusual thing. Quite often on forums like this uses are told to wipe their hard drive and reinstall Windows from a legal DVD disc. And that is what the OP attempted to do and it failed.
One would think that the OEM would like to cultivate good faith with its customers. There is no way to know for sure if this mishap was the fault of the OP, or if there is in fact some rare defect in the computer. The OP himself said he was not satisfied with the computer and this would imply something was not to his liking.
On that basis, in my opinion, the user should contact the OEM and provide a simplified story about how he had been told to reinstall Windows 8 again.
Although I personally doubt there's anything wrong with the hardware, there is no basis for making that assumption without first contacting the OEM. There is the rare possibility that he bought one of those computers that just turned out to be a lemon. It happens.
So, the best advice I can give to the OP at this point, is to contact the OEM and make a claim on their warranty provisions. Hopefully, they'll give you a and RMA ticket and you can return it to the manufacturer for repair or replacement. Of course, do not include any personal data on the hard drive. But at this point, there should not be any data left on the hard drive.
That's the best I can offer.
