|Use the Vista install disk to boot into the recovery console and let it try to do a startup repair. If that fails to fix the issue, then boot back into the install disk and perform a repair installation. It sounds like some driver files are missing or corrupted. You may also want to do a disk scan to ensure that there are not errors on the drive itself. |
Let me know if you need more assistance or have any questions.
