thankss papss, try ko po reset after maback-up yung files koWSOD = (white screen of death) mostly cause yan ng corrupted drivers or hardware problems and lastly malware virus.. the fastest solution is to format the pc and observe the clean installation. if wala na yung issue after a clean format then its either driver issues or malware virus ang cause.. but if still persist after a clean instal.. then may sira na mismo hardware mo.
