I hope this is the best place to post,
Anyway I have a pc that was running Windows 10 but it was getting so slow and kept crashing.
Then when I booted up it said preparing auto repair but after about 30 seconds it freezes.
I decided to do a clean install.
I have a Windows 10 pro full version dvd. I have changed boot order to boot from dvd first but although it says press any key to boot from dvd it does not.
Any ideas?
Welcome to the forum. Do you know the DVD will boot do you have another PC to test? When are you trying to boot from cold start or restart often it boosts so quick it won't load DVD. You could just do a full refresh and loose everything if you do a clean install it can mean thousands of updates.
Turning off fast boot may help from dvd
As Samuria has pointed out, it may not be a bootable dvd. If you're sure that it is, then disable "secure boot" in the bios, power down and restart with the dvd already in the drive. Some system specs would be helpful.it says press any key to boot from dvd it does not.
Do you have fast startup enabled? This can interfere with boot options.
What’s the make & model of the pc? Some have a dedicated key rather than using any key - this can be F7, F8 or F12.

Create a bootable disk (e.g. flash disk) as per the tutorial and use that.
Create Bootable USB Flash Drive to Install Windows 10
Here's the clean install tutorial:
Clean Install Windows 10
Note this entails deleting all existing O/S partitions
Blue text in tutorials is usually clickable.
What you need to do to get a given make of PC to boot from a bootable disk varies.
Sadly your specs only say 'Windows 10'
So use e.g. Google and search for e.g.
boot ASUS from bootable disk
Change ASUS as appropriate.
Option 2 here:
Boot from USB Drive on Windows 10 PC
Includes some models.
Noting your problems, you should first check your system disk and make sure it's ok.
To do that you'd need to connect it to another PC and then use a 3rd party program.
OR you could hope reinstalling Win 10 works, and then check (all your disks).
