Windows 7: Device Manager continually expands and contracts

Device Manager continually expands and contracts

I've got a problem on my month old custom build where the device manager screen continually fully expands then contracts to just the computer name. It may happen 2 or 3 times in succession then again in 15 or 20 seconds; no kind of pattern, but it won't stop. The only thing I can find out through my research is that it may (probably) be a driver trying to install itself. There are no errors or question marks in device mgr. and all devices 'say' they are working correctly. I have updated several drivers and they all completed successfully. My latency is good according to DPC Latency checker so I don't think it is a bad driver. I'm not sure exactly when the problem started but I know something is wrong and I don't have a clue of where to look or how to figure this out.

Look in the Event Viewer for clues when it happens.
Start menu> Event Viewer Hit Enter.
In the Event Viewer, look inside the Windows logs> System

If you don't see anything odd:
Try to systematically disconnect physical devices fro from your PC.
If that doesn't solve it move over to disabling your "Integrated Peripherals" in the BIOS
again one at a time.

Each time checking in the Devmgr to see if it has stopped.
If that didn't cut it, remove anything new you've installed since you noticed this issue.

Post back with results!
