After about 4-5 minutes of operation, the computer shuts off unexpectedly.Everything else appears to work OK, internet access, etc. It doesn't appear to be overheating, but can't be sure.

    joecoolvette, I did as you suggested regarding the fans. They are clean and free of any dust or gunk, and they are operating properly. I also took the fan and heatsink off the CPU to clean it, but
    I need to get more paste. As of the last attempts, the computer now shuts off during the boot process or shortly thereafter. I'm still open to any further suggestions. I do appreciate your help and I apologize for not getting back to you sooner.

Appreciate your getting back to me chanhuf.

If I understand correctly from your statement, did you state you turned the computer on with no thermal paste, on the top of the Processor's case? If so the Processor will overheat, and turn off. (BIOS turns it off)

If I have stated this already, forgive me.
The top of a Processor's case, and the bottom of a Heatsink are not perfectly smooth. A magnified view would show 'Pits, Hills, and Valleys'.

When the heatsink is set on top of the Processor, the voids mentioned above create air pockets.
Air is an Insulator, not a Conductor.

You want to Conduct heat from the Processor to the Heatsink.

[Typical construction of a Heatsink is a flat plate of metal, with tall, thin fins protruding from it.
The flat plate of metal, absorbs heat from whatever object it is placed against.
(In this case a Processor)

The tall, thin fins absorb heat from the plate, and the fins radiate the heat
When a fan is used in conjunction with a Heatsink, the air flow helps carry the heat away from the fins of the Heatsink ]

Thermal paste fills the voids. Thermal paste is an excellent conductor.

You did follow Anti-Static Precautions, correct? A Processor is the most
susceptible hardware computer component, to Static shock.

Awaiting your findings after applying thermal paste.
To add, there is a correct procedure for applying thermal paste.
(Thermal paste = Thermal grease)

A computer that shuts off unexpectedly is most of the time caused by heat. Check if the fan in the power supply is working fine by checking the back of the computer. You can take out the CPU too, clean it properly before adding a new layer of thermal paste. In this way, the heating issue will be eliminated.

My Sony VGC23E keeps shutting down unexpectedly.

What this could mean is that the CPU is controlled by thermostat to go off if the temperature gets a certain level. What I do when this happens is go to my local Radio Shack and purchase some heat sink paste for the CPU then I clean out the fan areas especially where the aluminum block is making sure all compacted dust is blown out.
More than likely it is time for a good cleaning and some heat sink paste on top of the CPU and sandwich the aluminum piece back together with paste in between this should assist with the shut down intermittently. John

How to fix unexpected shutdown due to Blue screen problem of Pavilion HDX9494NR

See if the Check disk utility will solve your problem. To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.

In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command.

It is not yet the end for your machine. The error codes refers to a faulty hard drive. You'll need a new hard drive for replacement and that will fix the problem.

Should you have any other questions just leave a message.

All the best!

HP Probook 6560b BIOS doesn't recognize working WD SATA HDD. I have verified that it works in another computer and two other SATA HDD's work in my Probook. I have a WD Black 500GB SATA HDD (model #WD5000BPKX) that was the Kubuntu OS drive in my old HP Probook 6550b and works flawlessly when I test it in my husband's HP DV2000, but the BIOS on my current HP Probook 6560b does not recognize it. Running a HD test within the BIOS returns no drive installed, however booting from Ubuntu 16.04 and 18.04 Live USB sticks shows the HDD in the OS's file manager and partition manager, and another (Seagate) SATA HDD works flawlessly in this laptop. I have restored the BIOS to defaults and the version showing within the BIOS - F08 - is newer than the one shown for Linux on HP's driver site. Are you aware of any incompatibility with this particular model of HDD? I have VirtualBox but no Windows computer, if it is advised to update the BIOS to the current F67 revision shown for Windows computers on the HP support site. EDIT: Solved. I had no access to a Windows computer, but figured for whatever reason the BIOS in a computer that shipped with a 500GB SATA HDD wasn't recognizing a 500GB SATA HDD. So I installed the original Windows Vista Basic on the older 320GB HDD, downloaded the current HP BIOS update for that OS (on my husband's Ubuntu computer, since of course Windows didn't recognize all of my hardware), copied it to the 320GB HDD, and installed it without a hitch. The Probook 6560b is now running under a fresh install of Kubuntu 18.04 on the 500GB SATA HDD that wasn't recongnized prior to that update. Maybe not the simplest way to resolve it, but at least it's fixed. Hope this helps someone else with an older laptop not recognizing their SATA HDD. :)
