PC Not Closing Down Properly
My desktop PC running Windows 7 64 bit behaves erratically when I close it down using the Start Orb - shut down button. Sometimes it closes down fully - on other occasions the computer goes into a deep sleep, (the hard drive light continues to flash, the fans are running, the monitor screen goes off) but it will not respond to either the keyboard or the mouse, both of which are connected by USB cables. I then have to close down the computer by holding in the power button for about 10 seconds.
When I next require the computer it boots normally and seems oblivious to its shut-down problem.
I always ensure that no programs are running when I shut down the computer and cannot see any clues regarding what I was last doing before shut-down that might trigger a problem.
I have tried uninstalling and reinstalling the USB device drivers to no avail.
Any other suggetsions?
