Some computers have a blade fuse built into them and that blows before the surge can burn anything out. Don't know if yours is like that so yep, a computer shop to have a look and reboot.
Hopefully that is all it is.
in the last month I had windows telling me I needed to update, put it off for as long a possible then decided to do it.
closed down all my files, or so I thought, set up 'restart', trundling along, 30%, 60%, 73% FROZEN, fuck. left it for several hours, still frozen.
switched it off and on, trundling along, 73% FROZEN.
Ring Geeks2U, bloke comes out, got to take computer away to run 'Microsoft Recovery Disc', can take 3-4 hours.
6 days later, has saved all my data and files from the HD, put in a new HD.
Got computer back, had 99% of my data and files, no emails, MS Outlook had corrupted and wiped all emails.
last Wednesday afternoon at 3.00PM windows tells me again I needed to update, set restart in motion, trundling away got to 30% FROZEN, fuck, fuck, double fuck. Ring Geeks2U bloke discusses situation and suggest might be time for a new computer.
Thursday morning the missus looks at the computer, still frozen. Turns it off and on, reboots perfectly, pos, go figure.
Bites the bullet, bought an new computer an in process of transferring all current work and data to it.
The outcome was that the CPU in the old computer is not supported by MS Windows 10 anymore and this causes it to freeze, and it's only good luck if it does a full successful reboot.
Could be a problem with yours if it is some years old.
Im led too believe that Windows 7 is still ok on old and new CPU's.
Just a thought.
