I recently restored my computer to the factory settings. Once the recovery disk got to 100% complete it populated the error "error #45 CRC error in data". I then hit OK and it rebooted the computer. It then asked me to take the CD out and it would reboot again. Once it rebooted, it is bringing up the error "invalid system disk, replace the disk, and then press any key". Can anyone help me, or should I take it to a computer repair person?
