After waking my Windows 7 Pro desktop computer from sleep mode, it will go back into sleep mode in approximately 10 seconds. This behavior repeats until I shut down and restart. I have noticed that system sound is muted (icon in notification area) just before entering sleep mode but only once in the aberrant wake/sleep cycle. My computer is set in BIOS to start from keyboard or mouse. I restored C drive from a Windows Backup Image but it did not go back far enough. I think the issue started the day before my scheduled backup. I have a cheap standard key board with no sleep key and a Logitech Performance MX mouse. The issue persists with both keyboard and mouse unplugged. I have checked advanced power settings but nothing stands out. I am going to uninstall a bunch of drivers in Device Manager as soon as I complete "honey do" list. How to proceed?
Updated AMD Radeon 7700 series driver. No change.
