My PC had been happily working on Windows 7 Ultimate 64bit, and all drivers were working fine.
I ran an upgrade check and all seemed ok to run the Windows 8 Pro 64bit upgrade, keeping my settings. So I did not do a full clean install.
I kept all my settings when I carried out the Windows 8 Pro 64bit upgrade.
Everything seemed to work fine, and the PC restarted without incident and also I checked for Windows 8 updates, which loaded fine.
All my devices appear to be working, but when I select the power option to SHUTDOWN my PC it goes into shut down, my screen then shows no signal, but the actual PC does not turn itself off.
I have to manually hold the power button in on my PC before the power will switch off.
I have disabled "Turn on Fast Start Up" feature, but this does not seem to have fixed the problem.
On boot up I then get an error message, and details of a file location.
Every time I switch the PC back on I get an error message and a reference to files in Minidump and also in AppData\Local|TEMP
I cannot open the .dmp files, and I cannot see the .XML file.
I am at a loss to understand how I might resolve this.
Has anyone any suggestions how I might fix this?
