I have an issue with my computer not displaying devices in device manager after an unknown period of time. This prohibits me from using the internet, unless a web browser was open before device manager has stopped. The only way to get the list of devices to view again is by shutting down the PC.
A restart will not work either. When I attempt a windows restart, or a cold restart, the monitor goes into sleep mode, and the red pc led light remains lit and the PC hangs with no further processing.
All of these problems go away if I shut it down and then start again. I am then able to restart, get online, and see the devices in device manager for only a limited time which seems to be a couple hours maybe, but the time frame appears to be random.
What can I do to resolve this situation?
