These errors can't be fixed by an application. The first error can be fixed using the built-in System Check. Go to Start > Run > Cmd and then type sfc /scannow. Any system errors will be fixed by replacing the corrupted files with the original ones (OS installation disk is required). The second problem can be fixed by installing official and signed drivers. If you're using a custom or a non-compatible driver, then you'll need to replace it.
