Whith is the difference between HP PC Hardware Diagnostics UEFI and Hardwar Diagnostic for Windows?

[grigtar]

THANK YOU FOR YOUR HELP AND SUPPORT !!!

I have Desktop PC HP.

I have HP Hardwar Diagnostic UEFI ver 7.6.1.0.1.

I know , that HP Diagnostics  UEFI 7.6.1.0 starts without Windows .

1. Do I need to additionally install HP Hardwar Diagnostic for Windows ver 1.6.4 ?

2.Is it enough to have only one program  HP Diagnostics  UEFI  7.6.1.0 ? (or it is better to install additionally HP Diagnostics for Windows ver 16.4 ?)
3. What additional functions does HP Hardwar Diagnostic for Windows have, which HP Hardwar Diagnostic UEFI does not have?

4.What additional functions does HP Hardwar Diagnostic UEFI have, which HP Hardwar Diagnostic for Windows does not have?

THANK YOU FOR YOUR HELP AND SUPPORT !!!

@grigtar , welcome to the forum.

I have reviewed the explanations for both apps.  It appears to me that they both do the same testing with the exception that HP Hardware Diagnostic UEFI ver 7.6.1.0.1, as you stated, operates from the BIOS/UEFI; not from Windows.  This allows it to test the components better because they are not fully functioning as they would be if the computer had booted to Windows:

"HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that provides diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs outside the operating system so that it can isolate hardware failures from issues that are caused by the operating system or other software components."

It certainly won't be a problem to have both on your computer at the same time, but I personally like to do the tests from the BIOS/UEFI.  I have found over the years that at least 85% of computer problems are caused by the software or drivers.  Knowing how the hardware is functioning lets me know if I should check further.

THANK YOU VERY MUCH FOR YOUR HELP and SUPPORT !!!

I am sorry for the trouble!

I have any questions:

1.For my computer

https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-gaming-desktop-pc-690-0000i/19769765/mo...

  I found version HP PC Hardware Diagnostic UEFI- 7,6,0,0. 
And on the site https://www8.hp.com/us/en/campaigns/hpsupportassistant/pc-diags.html

there is version  HP PC Hardware Diagnostic  UEFI- 7,6,1,0,
Which version do you recommend using AND WHY ?

2,There are two choices on the HP Hardwar Diagnostic page

https://www8.hp.com/us/en/campaigns/hpsupportassistant/pc-diags.html

Photo below/

a)-Download for Windows 10 ver.1.6.4

b)-Download for Windows 7,8,1 and 10 ver 1.6.4

1. What should I choose and install? How can I explain this?
2. What is the difference between the two choices?

If I use a)  Download for Windows 10 ver.1.6.4 I don't see HP PC Hardware Diagnostic for Windows  in the window of installed programs on the computer.

If I use b)  Download for Windows 7,8,1 and 10 ver 1.6.4 I see HP PC Hardware Diagnostic for Windows  in the window of installed programs on the computer.

How can this be explained?

3.Does the program  HP PC Hardware Diagnostic UEFI

or  HP PC Hardware Diagnostic for Windows check the computer's RAM ? (or is it better to use a separate program MemTest 86?)

THANK YOU FOR YOUR HELP AND SUPPORT !!!

You are very welcome, @grigtar!

Personally, I would use the one that states it is for Win 10, since this is what your computer is running.  I am not familiar enough with either version to be able to tell you the difference, however.  I do believe that either version will do what you want to do. 

I would download both versions and run a test with each to see what they test.  If you don't feel either is doing what you need, you can always use a third party app, such as, MemTest 86, as you suggested.

As I stated in my previous post, I like using the version that tests the components from the BIOS/UEFI.  It tests independent of Win 10.

You are welcome, @grigtar!

1) As I explained in my previous post, the Hardware Diagnostics UEFI (7.6.1.0 Rev. A) tests the components without booting to Windows.  This good for times when you can't boot into Windows for some reason, also.  This eliminates Windows from any influence on the test.  The 7.6.1.0 is an update for 7.6.0.0 that is in the Software and Drivers page. So, install 7.6.1.0.

The Windows Hardware Diagnostics (1.6.4.0 Rev. A) tests the components after the computer boots into Windows.  You can install both versions if this is what you want to do.

2) I would install the version for Windows 10.  The version for Windows 7,8.1, 10 would be used if your computer had those Windows version installed before installing Win 10.  At least, this is how I interpret the situation.

This is all of the information that I can furnish for you.  I hope this helps.

You are welcome, @grigtar!

I would use this site:  https://www8.hp.com/us/en/campaigns/hpsupportassistant/pc-diags.html

It is the official website for the diagnostics app and is an update from the 7.6.0.0 on the Software and Drivers page for your computer, as I stated in my previous post.  It will not harm your computer.
