I turn on my HP Pavillion desktop, it starts beeping and a yellow light is flashing on the front of the computer. There is a black screen on my monitor.

 Please help,if can.  Thank You.

Welcome to HP Forums, this is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand the computer is not booting into the windows anymore, instead you get the beeps and blinking lights in front of the computer with a black screen,

Don't worry I'd love to help, however, to provide an accurate solution, I'll need a few more details:

What is the sequence of the blinks? (Example: 3 blinks and then pause 3 blinks again, in a loop)

What is the product number of this computer and which Operating system have you installed? (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).

Have you performed any steps on your own before posting on the HP Forums?

In the meantime, Please click on the below links once you identify the blink code and resolve the issue:
