@Ram56 Note that specific patterns of long and short blinks along with long and short beeps (where applicable) identify errors during the startup process.
Newer computers have two-part blink sequences with different color lights to indicate specific errors and you may click here and troubleshoot on your own, or check below:

 

4 Blinks per second represents a Graphics controller not functional error, and I suggest you talk to HP support and discuss your options, follow the below steps to get started:

 

1) Click on this link - http://www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

 

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,

@Ram56 You will need to repair or replace the system board as the graphics controller is built-in, the best way to do the same, is to contact the support team as mentioned before,

If your device is not covered by any warranty, I suggest you check If you have an HP authorized service center near by, you should be able to take it to them and have it checked,

Here is a link to HP Service Centers, by Country/Region: Click here
