Laptop can't boot up, no display, fan run fast & light on the power button, wifi button

HP Recommended
HP 450 G3
Microsoft Windows 10 (64-bit)

Evening, i was using my laptop for 6 months and yesterday when i tried powering it on, it cannot boot up, the screens is just blank, fan run faster but i do have a light on the caps/number lock/wifi button/power supply and when i try to power if off by long pressing the power button it doesn't switch off unless i remove the charger/ac adapter. i tried to reset/put another ram module but i still get the same problem.

when i boot the laptop without a RAM i get 2 beep sounds from BIOS. i don't know what might be the problem because the processor is not overheating & fan is clean/ no dust. what do i do next? i tried to disconnect everything from the motherboard leaving the power button, fan and display cable but i still get the same problem.

@MASALA 

First off, the laptop will not boot without RAM -- so that is why you are getting the beeping because the memory is missing.

 

Second, 

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, then call and it may help speed up the call process:

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 - click on Get phone number

Case number and phone number appear.
--------------------
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 you don't get useful results using the Service Center link, here is the main HP link:

Good Luck

I tried changing the RAM i still get same problem. The heat sink is cool no sign of overheating to the processor . What do i check next?
