Running Windows XP Sp3 with all updates. After a recent boot up problem Device Manager stopped showing data, i.e. when open to view devices there is nothing there except a blank page. If left sitting for a couple minutes an error message comes up that MMC (Microsoft Management Console) has experienced an error. Is there any way to reestablish visibility in Device Manager without reloading the machine. I tried a System Restore roll back and running SFC /scannow without success. I really don't want to reload. The machine seems to be operating okay otherwise.
