Pc Not Always Booting

[fbg40]

Evening all,
Have a 4year old Lenovo all in one PC, basic specs are 1Tb HD, 8Gb ram, Intel i5 processor, W10 Home.Since the 8th April (been keeping a log) on the odd occasion the PC fails to boot (every 2 to 3 days). I then have to switch off using the power button, leave for about 30 secs then start again and all then seems fine.Could this be a sign that something worse is going to happen or should I not worry about it ? I have checked for viruses etc, and the HD has plenty of space left - I have only used about 10% of its capacity. Any info/help would be greatly appreciated.

What do you mean when you say it does not boot – is it as though no power has been supplied to the PC, or does the screen hang at some point?

May be worth running a disk check to see if anything is close to failing.

There is a possibility that its a bios battery - is it keeping time well.
Do you see any other error messages.

It started on a Wednesday. Chances are there's a Windows update trying to install itself. Try just leaving it switched on for a couple hours and see what happens. Sometimes updates give no message that they are installing, it just looks like the machine is doing nothing.

Run Startup Repair, as follows:

Click Start

Click Settings

Click Update & Security

Click Recovery

Under Advanced Startup, click Restart Now

Click Troubleshoot

Click Advanced Options

Click Startup Repair

Select your account (if necessary)

Type your account password (if necessary)

Click Continue

If there's a problem with your Startup files, it should be fixed. If you see "Start Repair couldn't repair your PC", it means that no problem was detected.

Then, irrespective of whether a problem was detected by the above, run a disk check as well:

Click Start

Type cmd in the search box.

In the results field above, RIGHT-click on cmd and select Run As Administrator

Then, assuming that your hard drive is Drive D on your computer, type CHKDSK d: /f (NB: There's a space in there after the K and another one after the colon)

Hit Enter

Carried out Start up repair - "Start Repair couldn't repair your PC". On your suggestion tried CHKDSK and got the following :
Chkdsk cannot run because the volume is in use by another
process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N) Y

This volume will be checked the next time the system restarts.
Will update you as and when.
Hymie : nothing appears on the screen although I can hear the HD whirring.
OG : Please see update below.
CAC : Time is fine, no error messages.
Chair : According to "Update and security" in settings I am up to date .
Once again, thanks for your help.

Just re-booted the PC, CHKDSK went into operation (sounds like military manoeuvres !) and now will just keep an eye on things over the next few days. CHKDSK said "Drive C checked and repaired " (or words to that effect !) Thanks again

Thanks for the feedback, Fbg40.

I'll keep my fingers crossed for you ;-)

Buenchico and all the others that kindly responded to my question last week : Glad to say that since last Sunday when I carried out B's suggestions (and OG of course !) all has been well. No problems in starting /booting up - hope I'm not tempting fate !! Thanks once again folks.
