Hello there,
NOTE: I only recommend ccleaner for cleaning junk files NOT registry. If you read where I recommend it, I said for cleaning junk files.
However be careful if you are going to use it. Create backups and system restore point before use.
If all above failed to solve your problem then I would ask following questions:
- Before this problem, were you able to create thumbnails for 3D videos?
- When did this happen ? The problem might have caused by a third party program that has damaged your system or it could be something do with your graphic driver ... Just to be clear, when it crashes, do you get any blue screen message? or any errors that
can help?
I haven't installed any new software since late 2012 except Video driver and Sound driver in which I kept backups of the drivers and have reverted back as far as 2010 with no change. Unless you count MS updates for the OS and MS Security in which I cannot go
back that far.
System restore only allows Me to go back about 8 Days. But drivers I can uninstall and install older Versions.
Last time I had a look in my 3D Video folder was about 3 months ago some of the files failed to generate thumbnails but no problem with dllhost.exe com surrogate saturating all of my memory.
Yes if I let dllhost.exe to continue consuming the memory it will eventually will Blue Screen and restart.
This is what I get in event log after reboot.
