Rather than a clean boot, I suggest testing in
Safe mode - ElevenForumTutorials
because that is a specifically MS-only form of Clean boot and is a lot quicker.
- I never use Option 2, the MSConfig method, to get into Safe mode because I was once trapped in a limited-boot mode after using MSConfig.
- As glasskuter points out below, Safe mode is more limited in scope than Clean boot but Clean boot can be used iteratively to dig down further to identify a specific cause.
If it also fails in Safe mode then I suggest using / creating another user account and testing it in that.
- If it works in another user account then the conclusion must be that the original user account is corrupted.
- The remedial action is then to stop using that original user account.
- Use another user account and make it an Admin one if required.
- Always make sure you have at least one spare, functioning Admin account so you'll know you'll always have the ability to create new accounts in cases like this.
- Personally, after having seen so many reports of user account corruption during Windows 7 days, I always keep two spare, local, Admin, password-protected Admin accounts so that one of them can be kept pristine, never logged in to and therefore imprevious to corruption [user account corruption happens in use not while the thing is just sitting there unused].
- User account corruption cannot normally be fixed but I did once see a claim that it was fixed by repeatedly relegating the original account to a standard one then promoting it back to an Admin one then relegating it again then promoting it again, then .... Apparently, after six cycles of this relagation-promotion, the user account started performing correctly again.
If it also fails in Safe mode and in another user account then I suggest running a Repair install [aka In-place upgrade]

Whilst a Repair install should not affect installed applications or your own files, I always do a full backup first [including a new system image] so I can at least get back to where I started from if it all goes haywire.
If it still fails in normal mode, in Safe mode & in another user account after completing the Repair install then I'd run Clean boot procedures.

- You might have to run this several times with iteratively-changed startup items in order to identify the culprit.
- This would still be preferable [for most users] to a Clean install.
