Your latest post and your original question seem to be two different problems! Your original question had to do with the DgiVECP driver errors. Your latest seems to be about system crashes. There also seem to be posts that have to do with NEITHER problem.
Is the original problem that you created this thread for (the DgiVECP issue) fixed?
If not, please see my post four above this one. It explains what DgiVECP is, as well as showing you how to both disable it and delete it.
Again, I suggest just disabling it first, although, if it's not starting then there's obviously nothing using it, so it should be safe to delete. Regardless, simply disabling it will get rid of the error messages.
Also, as a system administrator, I HIGHLY recommend using the "SC" command rather than editing the Registry directly, as others have suggested! There may be other changes that need to be done to the registry than those suggested by others, and the SC command
will take care of them automatically.
Furthermore, changing the Registry, if you don't know EXACTLY what you're doing, has the potential to be catastrophic!
Finally, using the SC command is easier, as you can cut and paste the command line (either disable or delete) from above
Hope this helps!
