random windows keep opening and wifi turns on n off. caps lock goes on n off. types stuff on its own

[Ashoktut]

Hi all, recently i had installed a win10 pro.. but it keeps opening windows and internet tabs randomly, it also toggles my wifi on and off so i lose internet connectivity and i cant manually toggle it back on. also the caps lock goes on and off and types random stuff on any text related area in the opened windows or internet tab. i have updated all drivers and all windows latest updates and antivirus updates, i have also used malwarebytes and hitman pro and cc cleaner for the registry. the laptop also slows down tremendously and gets hot while this happens. i have tried reinstalling windows but during the setup i can see the caps lock light going on and off. the windows wasnt original as it had some file on the desktop written aktivator. recently i cant even press esc for startup options and i get a cmos 502 messsage. current bios version is F.07   .i am kind of lost as i have tried to my knowledge. i do not know if this is software or hardware related. kindly share any information related to this matter. much appreciated. model is hp dv7 4050ei. product number is WY022EA#ACQ

That error indicates BIOS error.

Do a hard reset: https://support.hp.com/in-en/document/c01684768

See if it is corrected.

Install this:

Then try recovering BIOS by key press combination and if no joy from flash drive:

Only BIOS file available for this old model is compatible with Windows 7:

So you've to factory reset to Windows 7 before recovering BIOS. Use HP recovery discs for this.
