When i boot my computer now it comes with an error saying missing file or shared dll Program Files/x86 Nos32/somethingsomethingsomething. It still works it justs comes up w/ that error when i boot it and my computer is strangly slower
Check for the repeat errors in Event Viewer>Admin view to google text and ID# to find how others have resolved it.
If possible find out which Program is generating the .dll error to uninstall (or System REstore to before it's install) and then reinstall it. Or if you recently uninstalled a program before this began, reinstall it to see if it stops, then uninstall it again using Revo Uninstaller.
Uncheck everything except your AV and gadgets/stickynotes in msconfig>Startup as other programs are freeloaders on your RAM/CPU at all times and can spy on you. If you use a factory connection manager, etc., change to Win7's superior utility.

Likely a small glitch somewhere you were able to see taken care of fast. You may still want to review all of the startups in the system configuation or msconfig utility in case this was software related.
