Desktop random freeze OR reboot

[stoopid_mike]

In the past two months or so, the computer has started to display behavior that I am at a loss to explain or to repair. At random intervals, the machine will do a small freeze, where inputs from the mouse or keyboard fail to register on the screen. If I am listening to music, the music will either stop for three to five seconds, or will enter a short loop, or it may simply slow down the playback. Upon the “completion” of this disruption, the computer will return to normal. And, in ten to thirty minutes or so, it will repeat the sequence. About every third time this occurs, the screen will go black and the machine will completely reboot, so that I will have to log back in and restart any applications that I WAS using.

In a vain attempt to “repair”, I have gone to the HP hardware Diagnostics, the HP Support Assistant, upgraded what seemed to be in need of upgrading, and stared at the HP diagnostics windows for weeks, months on end and yet, within thirty minutes of hopefully resolving the problem, “POOF” another uncommanded REBOOT.

@stoopid_mike, Welcome to HP Support Community!

 Let's start with performing a hard reset on the PC to release any excessive static/power that could have caused the issue. 

  

Turn off the computer. 

Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers. 

Unplug the AC adapter from the computer. 

Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory. 

Press the Power button to turn on the computer. 

If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key. 

  

Second, you can check if there is a Bios update available for your PC, here is the link to download. 

  

Performing a test on the Hard drive as well as on the Memory from the Hardware diagnostics:  

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click Extensive Test.

5. Click Run once, or Loop until error.

   While the test is running, the time remaining and test result for each component are shown on the screen. The test can take 2 or more hours to complete.

   NOTE:

If the diagnostics are not available when using the F2 menu, run the HP PC Hardware Diagnostics from a USB drive. To download the latest version of the diagnostics, go to the HP Hardware Diagnostics website. For instructions, see Testing from an external USB device.

Depending on the test results, If the test passes then I would suggest you perform a complete system recovery.  

Note: Recovery will wipe off everything from the computer. If you have anything important get in touch with some local stores to get your data backed up.
