I have just come back from a week-long vacation and fired up my computer. When I left, the computer worked fine. When I turned it on today, it started fine, allowed a single pop-up that MalwareBytes had expired over the week (I planned to reinstall when I came back), and then immediately froze. I tried using Ctrl-Alt-Delete to open task manager and the computer froze again. After about five minutes, task manager opened and I saw that my memory usage and CPU usage were both normal. The computer then froze again. While task manager continued to display new information, I could not change tabs on it or open anything else. Eventually, I was forced to hard shut down. Every time I have restarted, the same problem occurred: the computer remains frozen for five to ten minutes before a command succeeds, and then it goes back to being frozen.
I am running Windows 7 64 bit, with 4 AMD processors and a Nvidia graphics card. I don't know the exact models off the top of my head and my computer is too frozen for me to find out, though they are up-to-date and I haven't had problems before.
Can anyone help me?
