Could you do the following please.
- Open a Command Prompt (Admin).
- Type: chkdsk /f and hit Enter.
You'll get a message that a diags check can't be run because the volume is in use and whether you want to perform a scan on the next restart. Type Y and hit Enter.
The scan will only take about 5 mins usually after which the system will boot to the desktop.
- Next step is to right click the Start button and click Event Viewer.
- Expand Windows logs and click Application at the top to select it.
- Right click Application and click Find.
- Type: Wininit and click Find Next.
- When it finds the log file right click that and click Copy ---> Copy details as text.This will copy the log contents to the Windows clipboard.
- Come back here, right click and click Paste.
If you want to keep a copy for yourself open Notepad right click in that and click Paste.
The object here is to check whether your hard disk has any errors on it which might be interfering with both Windows Update and the time server.
