I have a hp pavillion p7 1421 running win 8 on it and every time I turn it on it freezes with 2 to 3 minutes. I hit it with malawarebytes and McAfee but it just got worse. Its even freezing in safe mode and now I'm afraid to touch it. It even froze when I tried a system restore ITS THE DEVIL I TELL YA!!! The only thing I can think of is a Factory set reboot of the computer. But I have to buy a reboot disk for that plus I want to upgrade to win 10 so should I buy a win 8 or win reboot for this problem or is there a solution I'm not thinking of??????????????
