This just started today (I think), and it is weird.
I click on the start button, and then right click on Computer, and select Properties.
The Control Panel main screen comes up for just a second, and then closes and Windows Explorer restarts.
The computer itself does not reboot. The desktop just goes away and comes back, as if the computer has rebooted.
I have run Malwarebytes and a Virus Scan on the computer. Both found no problems.
I am currently running a quad core AMD A8 processor and Windows 7, with 8 GB of ram.
