So. This problem occured on both mine, and my friend's PC. Our PCs differ pretty much (specs at bottom). Basically, it takes forever ... literally, OR really long to restart or shutdown.
I have enabled the "VerboseStatus" registry key, to see what's happening. The only thing I discovered by doing this, is Windows is stopping at: "Notifying services ..." OR at "Shutting down"; but it doesn't happen always.
What I tried:
- Checking drivers. Bios. Updated my Bios to the latest stable. Audio driver removed, installed the Gigabyte version. Same with INF update, etc. Removed nVidia beta driver too, installed the stable 280.xx one.
- Checked services, network adapters. Nothing suspicious. Removed Avast!, nothing.
I suspect some software issue, but I have no idea what might be the cause.
The installed updates.
If you need any further information, please comment, and I'll add the requested stuff ASAP.
