I have been having a strange problem with my PC.
1/ On power up the audio turns on full volume.
2/ Windows update gets stuck.
3/ When opening file dialogs I get "Working on it" message forever but no list of files ever appears.
4/ Power down takes 5 minutes.
The problem occurs with all drives so its not a hard disc fault.
I have done a clean install of Windows.
I have put in new memory in case it was that.
Despite open file dialog just displaying "Working on it" I can open or save files by typing n their names in input box.
Yesterday I removed Norton anti virus and for a day now I haven't had any problems.
What is odd is it doesn't always have all these faults. Sometimes when I power up it is OK. It goes wrong about 50% of the time.
Any help or suggestions would be appreciated.
I am using Windows 10 pro with Skylake processor and 8gb ram.
