documents
Possible causes
Loose connection, faulty hardware.
Troubleshooting steps

2. Reset BIOS to default (9. Soft reset (Default Settings) on page 96).
3. Verify drive connection and ex cable. Reseat connection (10. Reseat cables and
connections on page 96).
4. Use the HP Hardware Diagnostics tool to test. If failed, record failure code and have the
hard drive replaced.
5. If no error with HP PC Hardware Diagnostics (UEFI) tool, try to repair the hard drive and
its les in Windows (using command “CHKDSK /f /r /x”). Use HP Restore to
reinstall the operating system, if needed.

1. Transfer data from the hard drive to create more space. Microsoft recommends at least
200 MB to sync system les.
2. Perform disk defragmentation to consolidate fragmented data on the hard drive so it
will work more eciently.
NOTE: Do not defrag an SSD.
Tips & tricks For optimal system performance, you need to place your operating system and all of your
most commonly used applications and les in the fastest hard drive (solid-state drive) and
fastest areas on the drive (primary partition of 200 GB max).
See Improving System Performance. Also see Routine Maintenance for Performance
Improvement on page 147).
Blue screen (BSOD) error
Faulty hard drive may cause blue screen error. Perform the drive tests using the HP Diagnostics Tool to make
sure the drive is functional. If all of the tests pass, see Common Blue Screen Error Messages on page 147 for
