- When you turn the computer on, it successfully launches to the HP loading screen (HP logo) but Windows fails to load. Windows may simply hung or PC boot process may end up with a Blue Screen of Death
- The computer may actually load properly but may be running slow and occasionally freezing or crashing
- Data stored locally may be corrupted or inaccessible
- After starting the computer HP's built in hardware diagnostics may display an error code for hard disk failure or missing (DST tests)
- Please, shutdown the computer using the power button (pressed and hold for a few seconds until PC powers off)
- Power the computer back on.
- Choose F2 to load the System Diagnostics.
Video of the entire process can be seen in the HP's channel in YouTube >here<
- If there are no system checks/no quick tests, you can perform Storage / HDD (hard disk drive) check.
- If the test finds no errors but your computer still exhibits symptoms of a hardware problem, run the Extensive Test.
- If a component fails a test, write down the failure ID and post in the HP Support Community.
If the short DST check of HDD or the extensitve HDD failed or resulted in "no disk/not found" , this means that issue is related to faulty HDD component. The faulty component needs to be replaced.
Since this is faulty HDD, you will probably not be able to recover or access your files. You can try to but there is no guarantee.
With regards to the replacement of the faulty hardware part - your options are:
1) If your computer is still under active warranty, please contact HP Support and inform them. They will work with you about the way to replace the faulty component for free . Contact HP:
2) If your computer is with warranty period expired, you will need to replace the faulty HDD - buy it on your own. There are variety of options - vendors you can choose from. You can get it online or from PC retail store, or from HP parts store http://partsurfer.hp.com/
You may also consider installing an SSD instead of an HDD - this is strongly recommended as SSDs are way faster, more repliable and lighter. More information about SSDs:
- You need a HDD with the very same size as the existing one or bigger (smaller will not work) - e.g. if your current HDD (or SSD) is with 500 GB capacity, your new HDD/SDD must also be 500 GB or with bigger capacity.
- You may find information how to replace the drive by reading the respective Service and maintenence guide for your computer model - available online in http://support.hp.com
- If you do not want to do this on your own, please bring the computer (or ship it) to HP Authorized Service Center where the technicians will do this for you. If you are not sure where such a center is located, check these or contact HP for assistance in finding the nearest one.
3) Last part - once you replace the faulty HDD component - you will need to reinstall back your operating system
