There is no such file as winnt32 in C:\.. Or there shouldn't be at least.
What you need to do is boot into safe mode and see if it makes your computer usable or not. If it does, then it will make it much easier to get rid of your problem.
To boot into safemode, tap the F8 key right before / during the Windows logo appears. You will see a text menu with several options, one of which will be safe mode.
