Do a full check disk.
If no errors are found do a sfc check.
While you're at it, use a boot cd/usb from any antivirus company (AVG/Avast are free), and do a full scan.

If already not tried, make this registry changes and see it resolve the issue?
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main] "Enable Browser Extensions"="no"

Hope this helps.

Nothing wrond with SSD and sfc came clean.  Already scanned with Malwarebytes and MS Security Essentials.  Found some common thing, quarantined and deleted.  Didn't fix an issue though.

Rad, I don't have that IE key you mentioned.

Also interesting that FF crash produces a different event log than IE or Chrome:

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

I think it is time to check your memory with Memtest86+
I had a very similar issue, but I didn't test with other browsers as the user only had IE installed.  Running IE in safe mode didn't help, reset all IE setting, didn't help.  Try these if you haven't though.

What I finally did was manually deleted all files from their internet cache (Using the delete button in IE didn't help either, but you can try it by going to the properties of IE without launching it.)

The folder (hidden and/or system) can usually be found in c:\users\username\appdata\local\microsoft\windows\temporary internet files.  I recommend (At your own risk) by doing this at a dos prompt.  Change to this directory and enter rd . /s /q.  This will remove all files and subdirectories.  Just be sure you're in the correct folder.

This finally worked for me, at least for IE.

I already deleted temp int files.  Restarted IE.  No luck..

Full scan seems solved the issue.   Virus was a culprit.
