Mouse/Computer Freeze & Action Center Msgs

All of a sudden my Windows 7 Home Premium computer has been acting up with a series of symptoms I could not all fit in the subject line.

1. The first thing is that clicking the mouse (Logitech M510) would not work or open an icon or menu. Then the pointer typically turns into something like a hand, or a spinning blue circle that never ends.
2. It generally happens when the browser is open, and I am working in it, but has happened in MS Word. The document becomes unresponsive to commands, the Word application becomes dim and grayed out (still clear), and at the top, it says something about Word "not responding".
3. I have a red X on the Microsoft Action Center. Yesterday , three messages were there, one about insufficient backup disk space, and two about a problem with the video driver. This morning, there are six messages:
   - Sypware and unwanted software protection (Important).
   - Virus protection (Important).
   - Solve a problem with AMD -Display Adapter - ATI Radeon Graphics.
   - Solve a problem with AMD/ATI video driver.
   - Install your vide card driver.
   - Check backup disk space.
   I installed the most recent driver and software for the R5770 card, but no change in the messages.
4. The freezing happens after the computer has been on for at least 20 minutes or perhaps quite a bit longer (I have not measured).
5. Applications generally open when the problem happens are Microsoft Outlook 2010 and Internet Explorer 10.0.9200.16635.
