Using system Image external hard drive or system repair disc.

Perhaps you can delete the other identical post...? Thanks.

You can freely download any of the Win 10 build iso's and create a bootable medium to reinstall Win 10 or perform an in-place upgrade repair (with the same build and base language iso) as many times as you like.

1. Microsoft Media Creation tool (search for it)
2. Download tool here:
Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums
post #3 iso downloader.

Note there too some other valuable repair tools (posts #1, #2).

Given your symptoms, you might like to try the one in post #2.

I recommend you do the following before that:
1. First check your disk(s):
Download and run Hard Disk Sentinel (trial) (includes SSDs)
(This gives exceptionally good text comments)
Post a screenshot of its GUI using the Insert Image icon above your post.
If all disks are reported as good, continue.

2. Now check your file system:

From an admin command or powershell prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Post back the result, which you can get after a restart as follows:

My computer has been acting up....

Dalchina has given you a good lists of checks to perform before trying anything more drastic. Try them first, including the last one (a repair install) before trying to restore your system image. You may well find they fix your problems and you don't need to go any further.

I created a system image and a repair disc a month or so ago, but do not know how to use them to see if my problems could be fixed...

By 'system image' do you mean you used the 'Create a system image' option in 'Backup and Restore (Windows 7)'? If so, at the end of making the system image it offers to create a 'system repair disc'. is this the disc you referred to?

If this is what you have done, then booting from the repair disc boots you to Advance Start up, 'Restore system image' is one of options in 'Troubleshoot > Advanced options'. If Windows is working, you can also boot to Advanced Start up from Settings.

Also, can't I just reinstall windows? How do I do that without a CD. None came with the computer

You could Reset Windows, which performs a reinstall using the system files already on the PC as the source, removing all installed software other than Windows itself. Note that this includes any OEM apps supplied by the PC manufacturer, except if the PC was supplied by them with Windows 10 pre-installed. If it was supplied with Windows 7 or 8 pre-installed and you upgraded to Windows 10 then all OEM apps will be removed. In all cases, software you installed yourself will be removed, so make sure you have any product keys and install media you may need to reinstall it.


Edit: if this is the HP Pavillion 510-a010 in your specs, then it was supplied by HP with Windows 10 Home. A Reset should reinstall the HP-supplied drivers and apps.

Or you could use the Media Creation Tool to make the install media as an ISO file that can be burned to DVD or as a USB memory stick. Boot from this and you can do a clean install....

...but a better use for it would be to perform the in-place repair upgrade, which can keep all your user files, installed software and most of your settings.
