Hi, Shane , I think it is malware problem. He could download malware bytes and check for any malware and remove. If he is having avast, he could also check bootscan. Your idea of startup problem is also possible fix.If that is not, he could check his computer with ccleaner, malware bytes  Otherwise do the following
Press Start and select Run
 Type CMD and press Enter
 Type regsvr32 nvdxgiwrap.dll and press Enter
 you will get success message if it is properly registered
