My hp computer is very old now but it was running fine till last week but now it has developed some strange problem as it keeps crashing everytime I log in and after logging in to my account the blue screen start appearing and restarts my old computer after every five minutes. I called online repair centre but they could not give me any useful advice. If some have any idea or know how to fix computer â¦â¦I would really appreciate â¦..thanks a lot
