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.
--------------------
If the CapsLock key is blinking or there is beeping, read this HP information on the likely cause of the hardware failure based on the blinking or beeping patters.

For desktops, this HP thread describes the different blink and beep codes: https://support.hp.com/us-en/document/bph07107?jumpid=reg_r1002_usen_c-001_title_r0001
--------------------
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.

Here is how you can get in touch with support:
Step 1. Here is the link: http://www.hp.com/contacthp/
Step 2. Select the product type.
Step 3. Enter the serial number of your device or select let HP detect your product option.
Step 4. Select the country from the drop-down.
Step 5. You should see the HP phone support number or Chat option listed.

--------------------
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 outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

If that link does not provide the results you want then use the main HP link:

Good Luck

Check the beep codes. If it is out of warranty and you want to work on it yourself, try disconnecting the dvd, then the hard drive, then the ram, then the graphics card if it has one, then the cmos battery, in turn leaving them out,  with the power off of course.  There are lots of youtube videos on how to do this safely and if you are unsure use your phone to take videos of each item as your are doing it so you can get back.
