It all started when me and my girlfriend decided to watch matrix. I wanted to connect my laptop to the TV through the HDMI cable, so I did. once I connected to the HDMI, my laptop just froze. I disconnected my laptop and tried to execute the process in task manager, but my ctrl + alt + del did not worked so I disconnected from charger and took out the battery.

Once I tried to power my laptop on, the display would not turn on, but all the buttons on the laptop seems to be working. Few seconds after my laptop is turned on, while I press any of the key on the keyboard - they beep.
every single key beeps except (num lock, prt sc(wihich I assume may be scroll lock or whatever.) and more keys on the left side of the keyboard. - tab, caps lock, shift, ctrl, fn, win and alt button) these are the buttons that are not beeping.

I disassembled my laptop, changed my thermal paste, took out the battery out of motherboard to restart the bios, but it seems like nothing helps. I also tried various ways with changing ram slots. I tried to turn on my laptop with one ram slot than with the other one but it seems like nothing helps.


I am really asking for anyone who could help me in this matter. I would really appreciate your help.

SPECS:
HP Pavilion dv6 (beats audio version)
RAM 8 Gb (originally 6, but my friend gave me one 4Gb slot from hp )
i5 intel processor.
win 10 os
radeon HD 6000 series. I hope that helps.


I hope that helps to understand my problem. Thank you for your support
