Laptop SOMETIMES won't boot, fans turn on for 2 seconds, turn off again, turn on again etc etc

[Boyjo1]

One day I tried to turn on my laptop. Pressed power button, it lit up, fans started spinning, hdd too I believe, nothing happened on screen. Fans and everything powered down, power button LED turned off for a second, came back on, fans started spinning again for a second or 2 and powered down again, repeat forever. I took the laptop, shook it around a bit, hit it with my palm and boom, booted right back up like normal again. Now, sometimes it won't boot like I just described, sometimes it boots like normal and sometimes it gets to the HP logo and then the screen glitches like in the photo I have added. I have reseated the RAM and HDD. What could be wrong?

6) Try to turn on the computer and check, If the issue persists continue next step

Set BIOS default and restart:

1. Restart your notebook.
2. During startup, press F10 repeatedly until the BIOS menu is displayed.

Hi,

You are suggesting that I reset bios settings to default, and run a system diagnostics test. My problem is that my laptop won't boot (unless I shake it) which means both of these things are not possible. Now, I am 95% certain there is a loose connector somewhere in my laptop, and I have contacted the website from which I bought it and I am waiting on their response so that I can open up my laptop and go and find it myself because even though my laptop is out of warranty, if I open it up they might not help me. Because I am fairly certain it's just a connector that's bad, I don't think it's necessary to perform a full factory reset. I did perform the system diagnostics after pressing F2 on startup, everything was okay and my laptop passed the tests.

I understand your concerns.

Please perform the system reset and check.

Windows 10 has a reset feature that repairs your computer by reinstalling the operating system. This feature is recommended for recovery because it reinstalls Windows 10 while either preserving your personal data and customizations or removing all your personal data.

You have a choice of two methods to reset your computer.

• If Windows 10 loads correctly, see the section titled Perform a Windows 10 system reset in Windows in this document.

• If Windows 10 does not start correctly, see the section titled Perform a Windows 10 system reset through Windows Recovery Environment in this document.

Have a nice day!!
