I have attached an HJT log. On February 23rd I woke up to a very slow computer that would keep freezing and upon start-up, would go to a black screen before I'd have to reboot and then it would go to the desktop but it would still take minutes before I could access any folder. There were no problem with my computer before this, at all. Anything I've installed within the past week I have uninstalled. I could not go to a restore point cause my computer never made restore points. Please help.
