Try boot into safemode again, this time open the registry. (START --- RUN --- and type regedit)
Look in the following folder

Look for anything strange e.g. anything with these names:
Also run a search for these files:
? C:\WINNT\system32\in10b6s.dll
? C:\WINNT\system32\MB.dll
? C:\WINNT\system32\saie321.dll
Delete the files once found. (Windows doesn't need them)
