@lse123 

Most likely -- NOT.  The CMOS battery does not actually power the motherboard or the PC.  All it does is power the BIOS chip so the settings are retained when you power off the PC.  If that battery fails, you won't be able to save changed BIOS settings, but the PC will still boot.

 

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number:

Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options

--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
https://www.service-center-locator.com/hp-hewlett-packard/hp-hewlett-packard-service-center.htm

If that link does not provide the results you want then use the main HP link:
https://support.hp.com/us-en/contact-hp?openCLC=true

Good Luck

The problem reappeared

I suspect that

If this PC of 2008 model, remains for long periods ON and shutdown, and startup may do this on startup --- Turns ON but on startup and beyond --- neither bios text shown nor any other text bios or Windows 10 Home?

HP Pavilion Elite M9372.Gr Desktop PC --- Microsoft Windows 10 (64-Bit)

 

Later in a couple of days when start --- may start-up normally - shown bios text initially and after boot to windows 10 home...

 

MAy is Motherboard problem...?
