According to RegInOut, Dell error code 0146 means there are issues with the hard drive, or HDD, and Windows registry. It is recommended that code repair occur immediately.
A HDD stores the bulk of a computer's memory. The Windows registry is a hierarchical database that stores settings and options. The kernel, user interface and third party applications all make use of the Windows registry.
Damage to both the HDD and registry result in such symptoms as slow PC performance and system freezes and crashes, according to RegInOut. However, the repair difficulty level is considered easy, and users are encouraged to download the Intel Software Partner tool to repair scan the PC. Similarly, RegInOut's listing of registry corruptions accompanies its advice to download RegInOut Registry Cleaner to conduct a two minute scan. Experts also recommend repairing the HDD by using the Desk CheckUp utility. In addition, they say to use PSA Diagnostics, a built-in diagnostics program used to fix error code 0146 or conduct a system setup by restarting the system. If all else fails, the option to restore the system exists. System Restore aids in recovering reversible damage, such as configurations and settings.
