Windows 10: Laptop turning on and off randomly on its own

I have a HP pavilion laptop I recently tried to increase the video ram of laptop without installing any applications or new graphics card with the help of a tutorial on YouTube. Now,my laptop is randomly turning on and off on its own. I have tried doing a hard reset but it is not working. I don't know what to do please help.I tried to open bios by repeatedly pressing delete key,F1,F2,F11 key,etc as shown in the tutorial I mentioned above and this issue has been persistent ever since. I tried to do that BIOS thing and it is saying error 500When it turns on it is only for a couple of seconds sh

Laptop Randomly Restarts / Turns Off and comes on with No Wifi

Thanks for the reply

I dont get any errors when the laptop restarts, but it happens randomly and instantly everything shuts down with no warning. Its not like a restart because it doent say restart it just turn off. And sometimes switches ot self back on.

I dont think I have downloaded any applications to cause the problem.

Te problem happens randomly, i think most of the time when im using the internet or using cpu heavy applications. But i think it happens randomly.

I tried the troubleshootin and it doest have the wifi adapter when it randomly shuts down. It just shows ethernet and bluetooth adapter. When i restart it again wifi works.

 

Laptop turns off randomly

I use Open_hardware_monitor Extract to C:\Program Files (x86)\HardwareMonitor and run openhardwaremonitor.exe. Under options you can set to run on startup.

I have a 10 Year laptop that was overheating. I opened the case and removed the heat sink. It was completely clogged with dust.

If you use a vacuum cleaner or compressed air, use something to block the fan to prevent over spin

 

Windows 10 freezes randomly

I had already tried turning off fast startup, to no avail.
Will look at the list you provided, thanks. Hard to do when computer freezes on the Windows loading screen though. *Biggrin

I had tried that as well... no result.
