I left my other computer an hour ago with a few programs running. The only active program was my Backblaze cloud backup.
I've just returned and the clock is frozen at 10:11.
Task Manager is not shutting down the programs and I cannot shut down the computer via the Power button - it just won't respond.
Before I use the power switch to force it to shut down, anything else I should consider?
Hold ctrl-alt-del until it restarts?
When I got back to the computer, I was able to open Task Manger. But, it wouldn't close any programs.
Now, I can't close the Task Manager window itself. It's also blank.
So, holding down Ctrl/Alt/Del is no longer having any effect.
Try holding the Power Button for 3 seconds. If you do have to pull the plug, do it quickly to prevent it from arcing.
a mate had Blackblaze and whenever Safety Freeze kicked in, it would lock his entire PC (its not meant to do this apparently). There is a way through blackblaze to see what folder/file caused the safety freeze (if it was that).
